Fix a timeout or container that will not start
Error: Timeout / no response / container not starting
DNS is fine but nothing answers: the app container is down or traffic is blocked.
The container crashed or never started, or the firewall is blocking ports 80/443.
The fix
Check whether the container is actually running:
docker ps --format "table {{.Names}}\t{{.Status}}" | grep -i <your-app>If it is not listed or keeps restarting, open Coolify → the app → Logs / build logs and fix the start error, then redeploy.
If it IS running, confirm ports 80 and 443 are open on the VPS firewall (and the cloud provider’s security group).
