Problem Description

Issue

After enabling “Exclude from Firewall”, the Minecraft instance lost network synchronization.
Players can connect but cannot move, and plugins do not load.

Datastore repair was already performed, but the issue persists.
Requesting an application reinstall or container rebuild without deleting any files or data.

Reproduction Steps

  • Enabled “Exclude from Firewall” in instance settings.
  • The server restarted automatically.
  • Players can join but cannot move, and plugins do not load.

That sounds like expected behavior because Exclude from firewall removes the firewall rules added by AMP, causing things to not work correctly.
You need to leave that disabled, or add the firewall rules yourself if you want more fine-grained control.
