Symptoms Cannot connect to irc-direct.folk.zone:6667 or :6697 from external clients.

Cause Ports not exposed, firewall blocking, or router not forwarding.

Fix

1. Verify ports are exposed in docker-compose.yml
2. Check firewall allows ports 6667 and 6697
3. Test locally: nc -zv localhost 6667
4. Verify router port forwarding if connecting from outside LAN

Prevention Test connectivity locally before checking external access.
