Hi, I have Hetzner servers managed through Zeabur:
- Hetzner Falkenstein 16C 32GB — IP: 178.105.2.6
I accidentally enabled UFW without allowing SSH port 22 first, which locked me out completely:
- SSH: Connection timed out
- K3s agent: offline (Dashboard shows "K3s 離線中")
- Zeabur Dashboard SSH: also cannot connect
The fix is simple — just run on both servers:
ufw disable
Could you please help by either:
- Accessing the servers via Hetzner VNC Console and running
ufw disable - Or reinstalling/resetting the OS on both servers
Thanks!
