📞 TROUBLESHOOTING

Common Issues:

1. Webhook SSL Error in Mattermost:

# Solution: Use SSH tunnel
ssh -N -L 3001:localhost:3001 -p 2255 -i vps_hardening_key sysadmin@thebankofdebbie.giize.com &

# Then configure Mattermost webhook URL as: http://localhost:3001/webhook/btcpay

2. Bitcoin Sync Slow:

# Normal over Tor - check progress:
docker logs btcpayserver_bitcoind | tail -20

3. Onion Services Not Accessible:

# Restart Tor containers:
docker restart tor tor-gen
# Wait 5 minutes for new addresses

4. Storage Issues:

# Check Bitcoin pruning is working:
docker logs btcpayserver_bitcoind | grep -i prune
# Should show: "Prune configured to target 10000 MiB"
