Q: My node is unreachable even though it’s running. What could be wrong?

A: A common issue is an IP address mismatch between your environment file and your server’s actual public IP. This happens when:

  • Your env file has IPV4=X.X.X.X
  • But your server is actually registering from a different IP address
  • DNS records point to the env file IP, making the server unreachable

Fix

  1. Identify your server’s actual public IP address
  2. Update your env file to set IPV4= to the correct IP
  3. Restart the stack:
docker compose --profile ndt --env-file env down
docker compose --profile ndt --env-file env up -d
