Archipelago Troubleshooting Guide

This guide covers the 20 most common issues you may encounter with Archipelago, along with diagnostic commands and solutions.

Connection & Access

1. Can't connect to the web UI

Symptoms: Browser shows "connection refused" or spins forever when accessing http://<your-server-ip>

Diagnosis:

# Check if the server is reachable on the network
ping <server-ip>

# SSH in and check Nginx
ssh archipelago@<server-ip>
sudo systemctl status nginx
sudo nginx -t

# Check if the backend is running
sudo systemctl status archipelago
curl -s http://localhost:5678/health

Solutions:

• Ensure you're on the same network (LAN) as the server
• If Nginx is down: sudo systemctl restart nginx
• If backend is down: sudo systemctl restart archipelago
• Check firewall: sudo ufw status — port 80 (HTTP) and 443 (HTTPS) must be allowed
• If the server IP changed, check your router's DHCP lease table or run ip addr show on the server

2. Login page loads but login fails

Symptoms: You see the login screen but entering the correct password shows an error

Diagnosis:

# Check backend logs
sudo journalctl -u archipelago --since "5 minutes ago" --no-pager

# Test the RPC endpoint directly
curl -s -X POST http://localhost:5678/rpc/v1 \
  -H 'Content-Type: application/json' \
  -d '{"method":"server.echo","params":{"message":"test"}}' | head -100

Solutions:

• Default password is password123 — change it after first login
• Clear browser cookies and try again (stale session cookie)
• Restart the backend: sudo systemctl restart archipelago
• Check if the database is accessible: ls -la /var/lib/archipelago/

3. Web UI loads but shows blank white page

Symptoms: Browser loads but nothing renders, or you see a white screen

Diagnosis:

# Check if frontend files exist
ls -la /opt/archipelago/web-ui/index.html
ls -la /opt/archipelago/web-ui/assets/

# Check browser console (F12 > Console) for JavaScript errors
# Check Nginx error log
sudo tail -20 /var/log/nginx/error.log

Solutions:

• Redeploy the frontend: run the deploy script from the development machine
• Check if files exist in /opt/archipelago/web-ui/ — if missing, the deploy didn't complete
• Clear browser cache (Ctrl+Shift+R or Cmd+Shift+R)
• Try a different browser or incognito mode

4. HTTPS certificate warning

Symptoms: Browser shows "Your connection is not private" or certificate error

Solutions:

• Archipelago uses a self-signed certificate by default — this is expected on first visit
• Click "Advanced" > "Proceed to site" (Chrome) or "Accept the Risk" (Firefox)
• For permanent fix, configure a domain name and use Let's Encrypt
• On kiosk mode, the certificate is auto-accepted

---

App Issues

5. App won't start (container fails to launch)

Symptoms: Clicking "Start" on an app shows an error, or the app stays in "stopped" state

Diagnosis:

# Check container status
podman ps -a --filter "name=<app-id>"

# Check container logs
podman logs <app-id> --tail 50

# Check if the image exists
podman images | grep <app-id>

# Check available disk space
df -h /var/lib/archipelago

Solutions:

• If the image is missing: reinstall the app from the Marketplace
• If disk is full: run disk cleanup from Settings, or manually podman system prune
• If the container exits immediately: check logs for the root cause (usually missing config or permissions)
• Restart podman: sudo systemctl restart podman

6. App shows "unhealthy" status

Symptoms: App is running but shows a yellow or red health indicator

Diagnosis:

# Check container health
podman healthcheck run <app-id>

# Check container resource usage
podman stats <app-id> --no-stream

# Check container logs for errors
podman logs <app-id> --tail 100 | grep -i error

Solutions:

• Some apps take time to become healthy after starting (especially Bitcoin which needs to sync)
• Check if the app has enough resources (RAM, CPU)
• Restart the specific app from the UI or: podman restart <app-id>
• Check if dependent services are running (e.g., LND requires Bitcoin)

7. Bitcoin not syncing / stuck at a block height

Symptoms: Bitcoin node shows the same block height for an extended period

Diagnosis:

# Check Bitcoin logs
podman logs bitcoin-knots --tail 50

# Check if Bitcoin is connected to peers
podman exec bitcoin-knots bitcoin-cli -datadir=/data getpeerinfo | grep -c '"addr"'

# Check sync progress
podman exec bitcoin-knots bitcoin-cli -datadir=/data getblockchaininfo | grep -E "blocks|headers|verificationprogress"

Solutions:

• Initial sync takes 1-7 days depending on hardware — be patient
• Ensure the server has a stable internet connection
• Check disk space: Bitcoin requires 600GB+ for full chain
• If stuck: restart the container podman restart bitcoin-knots
• If peers = 0: check firewall allows port 8333 outbound
• Add manual peers: edit bitcoin.conf to add addnode= entries

8. LND won't connect to Bitcoin

Symptoms: LND shows errors about Bitcoin connection, or channels aren't working

Diagnosis:

# Check LND logs
podman logs lnd --tail 50

# Check if Bitcoin RPC is accessible from LND
podman exec lnd wget -qO- http://bitcoin-knots:8332/ 2>&1 | head -5

# Check LND status
podman exec lnd lncli getinfo 2>&1 | head -20

Solutions:

• Ensure Bitcoin is fully synced before starting LND
• Both containers must be on the same Podman network (archy-net)
• Check Bitcoin RPC credentials match what LND expects
• Restart both containers in order: Bitcoin first, then LND

---

Backup & Recovery

9. Backup fails to create

Symptoms: Backup button shows an error, or backup file is empty

Diagnosis:

# Check disk space
df -h /var/lib/archipelago

# Check backup directory permissions
ls -la /var/lib/archipelago/backups/

# Check backend logs for backup errors
sudo journalctl -u archipelago --since "10 minutes ago" | grep -i backup

Solutions:

• Ensure sufficient disk space (backups can be large)
• Check permissions: backup directory should be owned by archipelago user
• Try creating a smaller backup (exclude app data)
• Restart the backend service and try again

10. Can't restore from backup

Symptoms: Restore process fails or data doesn't appear after restore

Diagnosis:

# Verify backup file integrity
file /path/to/backup.archipelago
ls -la /path/to/backup.archipelago

# Check backend logs during restore
sudo journalctl -u archipelago -f

Solutions:

• Ensure the backup file is not corrupted (check file size is reasonable)
• Passphrase must match what was used during backup creation
• Stop all running apps before restoring
• After restore, restart the backend: sudo systemctl restart archipelago

---

System Updates

11. System update fails

Symptoms: Update button shows an error, or update process hangs

Diagnosis:

# Check internet connectivity
curl -s https://debian.org > /dev/null && echo "Internet OK" || echo "No internet"

# Check backend logs
sudo journalctl -u archipelago --since "15 minutes ago" | grep -i update

# Check disk space (updates need temporary space)
df -h /

Solutions:

• Ensure stable internet connection during updates
• Ensure at least 2GB free disk space
• If update hangs: wait 10 minutes, then restart the backend
• Do NOT power off during an update — this can corrupt the system
• If system is in a bad state after failed update: boot from the USB installer and select "Repair"

12. Server won't boot after update

Symptoms: Server doesn't respond after a system update

Solutions:

• Wait 5 minutes — the first boot after update may take longer
• If still unresponsive: connect a monitor/keyboard to check boot messages
• Try the recovery mode: boot from USB installer and select "Repair"
• As a last resort: reflash the USB and restore from backup

---

Kiosk Mode

13. Kiosk display shows black screen

Symptoms: Connected monitor shows black screen instead of the Archipelago UI

Diagnosis:

# SSH in and check kiosk service
sudo systemctl status archipelago-kiosk

# Check if X11/Wayland is running
ps aux | grep -E "(Xorg|weston|chromium|firefox)"

# Check display output
ls /dev/dri/
xrandr --query 2>/dev/null || echo "No display server"

Solutions:

• Restart the kiosk service: sudo systemctl restart archipelago-kiosk
• Check HDMI cable is securely connected
• Try a different HDMI port or cable
• Check if the display is set to the correct input source
• Review kiosk logs: sudo journalctl -u archipelago-kiosk --since "5 minutes ago"

14. Kiosk display is stuck or frozen

Symptoms: Kiosk shows the UI but it's unresponsive to touch/mouse

Solutions:

• The watchdog service should auto-restart frozen kiosk — wait 30 seconds
• SSH in and restart: sudo systemctl restart archipelago-kiosk
• Check if the backend is responsive: curl -s http://localhost:5678/health
• If backend is down too, restart everything: sudo systemctl restart archipelago archipelago-kiosk

---

Network & Connectivity

15. Tor address not available

Symptoms: Settings shows "Tor: Not configured" or the .onion address is missing

Diagnosis:

# Check Tor container
podman ps --filter "name=tor"
podman logs tor --tail 20

# Check if Tor hostname file exists
cat /var/lib/archipelago/tor/hidden_service/hostname 2>/dev/null

Solutions:

• Tor takes 30-60 seconds to bootstrap — wait and refresh
• If Tor container is stopped: start it from the Apps page
• Check that the Tor data directory exists and has correct permissions
• Restart Tor: podman restart tor

16. Peers can't reach my node

Symptoms: Federation peers show "unreachable" status

Diagnosis:

# Check if Tor is running (needed for peer connectivity)
podman ps --filter "name=tor"

# Check your Tor address
cat /var/lib/archipelago/tor/hidden_service/hostname

# Test connectivity from the server side
curl -s http://localhost:5678/rpc/v1 \
  -H 'Content-Type: application/json' \
  -d '{"method":"node.tor-address","params":{}}' | head -50

Solutions:

• Ensure Tor is running (required for peer-to-peer communication)
• Tor circuits can be slow — connections may take 30+ seconds
• Share your correct .onion address with peers
• Both nodes must have Tor running and be on the same federation

17. DNS resolution issues

Symptoms: Apps can't reach external services, container downloads fail

Diagnosis:

# Test DNS from the server
nslookup google.com
dig google.com

# Check DNS configuration
cat /etc/resolv.conf

# Test from within a container
podman exec bitcoin-knots nslookup seed.bitcoin.sipa.be

Solutions:

• Configure DNS from Settings > Network: try Cloudflare (1.1.1.1) or Google (8.8.8.8)
• If using custom DNS, verify the server addresses are correct
• Restart networking: sudo systemctl restart systemd-resolved

---

Performance & Resources

18. Server is very slow / high CPU usage

Symptoms: Web UI is slow to respond, apps are laggy

Diagnosis:

# Check CPU and memory usage
top -bn1 | head -15

# Check per-container resource usage
podman stats --no-stream

# Check disk I/O
iostat -x 1 3

Solutions:

• Bitcoin initial sync uses heavy CPU — this is normal and temporary
• Check which container is using the most resources with podman stats
• Stop apps you don't need
• If RAM is full: add swap space or upgrade hardware
• Consider using an SSD if running on HDD (massive I/O improvement)

19. Disk full

Symptoms: Apps fail, UI shows disk warning, new installs fail

Diagnosis:

# Check disk usage
df -h /var/lib/archipelago

# Find largest directories
du -sh /var/lib/archipelago/*/ | sort -rh | head -10

# Check Podman image/container sizes
podman system df

Solutions:

• Run disk cleanup from Settings
• Remove unused app data: podman system prune -a (WARNING: removes all stopped containers and unused images)
• Move Bitcoin data to external drive if chain data is too large
• Check for large log files: du -sh /var/log/*/ | sort -rh
• Consider upgrading to a larger disk

20. WebSocket disconnections / "Reconnecting..." banner

Symptoms: UI shows a reconnecting indicator, real-time updates stop

Diagnosis:

# Check backend health
curl -s http://localhost:5678/health

# Check backend logs for WebSocket errors
sudo journalctl -u archipelago --since "5 minutes ago" | grep -i websocket

# Check system resources (WebSocket can drop under load)
free -h

Solutions:

• Brief disconnections are normal during backend restarts — the UI auto-reconnects
• If persistent: check if the backend is overloaded (high CPU/RAM)
• Restart the backend: sudo systemctl restart archipelago
• Check Nginx WebSocket proxy config: /etc/nginx/sites-available/archipelago must include proxy_set_header Upgrade $http_upgrade
• If on WiFi, try wired Ethernet for more stable connectivity

21. LoRa radio firmware flash failed / board unresponsive

Symptoms: The "Erase & Flash Now" flow in the mesh hot-swap modal reports an error, or the radio no longer enumerates as a serial device after a flash attempt.

Diagnosis:

# Poll the flash job's last-known stage/error directly
curl -s http://localhost:5678/rpc/v1 \
  -H 'Content-Type: application/json' \
  -d '{"method":"mesh.flash-status","params":{}}'

# Confirm the board is still enumerating at all
ls -la /dev/ttyUSB* /dev/ttyACM* /dev/mesh-radio 2>&1

# esptool/rnodeconf binaries present?
which esptool; ls -la /usr/local/bin/archy-rnodeconf

Solutions:

• A failure during erasing/writing (MeshCore/Meshtastic) or autoinstalling (Reticulum) can leave the chip erased or half-written — this is expected risk of the "always erase first" default, not a bug.
• Heltec V3/V4 boards can be forced back into bootloader mode manually: hold BOOT, tap RST, then release BOOT — this puts the chip in a state esptool can always talk to, regardless of what firmware (if any) is currently on it.
• With the board in bootloader mode, a manual recovery flash can be run directly over SSH without the UI:

  esptool --chip esp32s3 --port /dev/ttyACM0 erase_flash
  esptool --chip esp32s3 --port /dev/ttyACM0 write_flash 0x0 <known-good-image.bin>
  

• For Reticulum/RNode boards, the equivalent manual recovery is archy-rnodeconf /dev/ttyACM0 --autoinstall (or /usr/local/bin/archy-rnodeconf if it's not on PATH) — it re-runs the same fetch+erase+flash+bootstrap sequence the UI triggers.
• If esptool/archy-rnodeconf are missing entirely, they should have been installed by the last self-update.sh run — check sudo journalctl -u archipelago-update for install failures, or install esptool via sudo apt-get install esptool directly.
• Once a fresh image is confirmed written, unplug/replug the radio (or wait for the next detection poll) — the hot-swap modal re-probes automatically and shows whatever firmware is actually on the board now.

Known incident (2026-07-23) — reconnect storm / device boot-loop after a failed flash: a real Heltec V3 got stuck cycling "connect → partial handshake → drop" every 5-15s for 5+ minutes after a mesh.flash-device attempt failed with Reading firmware download stream. Root cause was two compounding issues, both now fixed:

1. spawn_mesh_listener's reconnect backoff (core/archipelago/src/mesh/listener/mod.rs) reset to its 5s minimum any time the prior session had been device_connected at all, even for under a second — so a device that connects-then-drops repeatedly never actually backed off. Every retry's open() toggles DTR/RTS, which resets many ESP32 boards' MCU (native-USB and CP2102/CH340 auto-reset-circuit boards), so the aggressive retries were themselves causing the boot loop, not just observing one. Fixed by only resetting backoff when a session ran for at least STABLE_SESSION_THRESHOLD (20s) — see that constant's doc comment.
2. mesh::flash::start_flash_job's post-completion handler auto-resumed the listener unconditionally, even after a failed flash, immediately re-entering the reconnect loop above with no cooldown. Fixed: on failure the listener is now deliberately left stopped (reconnect manually via the UI once the board is confirmed alive); on success there's a 5s settle delay before resuming, so the board finishes booting from the flash tool's own reset before Archipelago starts probing it again.
3. Separately, the download itself was failing because mesh::flash's HTTP client had a blanket 30s request timeout that covered the entire download (including streaming a 170MB Meshtastic zip), not just connection setup — fixed with a per-chunk stall timeout instead of a fixed total-transfer cap.

If this symptom recurs (rapid repeating mesh::serial: Opened serial port... Starting Meshcore handshake lines in journalctl -u archipelago without a LoRa firmware flash job in progress), it's a NEW instance of the same class of bug, not the one above — check whether backoff is actually escalating (Mesh session error: ... (retry in Xs) — X should grow past 5s within a few cycles) before assuming it's flashing-related.

General Maintenance

Quick Health Check Commands

# Overall system status
sudo systemctl status archipelago nginx

# All containers
podman ps -a

# Disk usage
df -h /var/lib/archipelago

# Memory usage
free -h

# Recent errors
sudo journalctl -u archipelago --since "1 hour ago" -p err

# Backend health endpoint
curl -s http://localhost:5678/health

Emergency Recovery

If the system is completely unresponsive:

1. Power cycle: Hold power button for 10 seconds, then turn back on
2. Wait 5 minutes: Services take time to start, especially if containers need to recover
3. SSH in: If web UI is down but SSH works, restart services manually
4. USB recovery: Boot from the Archipelago USB installer and select "Repair"
5. Clean install + restore: As last resort, do a fresh install and restore from backup
