fail2ban Blocks Coolify Container After Repeated SSH Failures
Affects: Coolify
Symptom
After repeated failed SSH connection attempts during Coolify setup, fail2ban bans the Coolify container's IP, causing all subsequent SSH attempts to silently fail even after the key is fixed.
Check if banned
sudo fail2ban-client status sshd
Look for the container IP (typically in the 172.18.x.x range) in the banned list.
Unban
sudo fail2ban-client set sshd unbanip 172.18.0.7
