Got IO error working with :control.playit.gg

Hi everyone, first timer on this forum.

It’s been 3 months since I’ve used the playit plugin to create tunnels for my Minecraft servers. I host them inside Docker containers on a Linux workstation.

However, since a week or so, I’ve had the following issue:
Got IO error working with :control.playit.gg/[some IPv6], error : java.net.SocketException: Network is unreachable
Thus making the access to the server only through LAN connection.

Java is updated to its latest version, the Minecraft Docker image too, and I’ve downloaded the latest playit plugin available.
I can’t understand how it stopped working suddendly. I’ve searched online for a solution and tried many things:

  • Resetting the playit agent, clean plugin installation
  • Using a standalone version of the playit agent running side-to-side with the Minecraft server
  • Adding –net=host in the Docker run command
  • Changing ports of the playit tunnel

Has playit updated its API, DNS or something? Is the plugin out-of-date?

If you’ve got any clue to what has been the source of this issue or how to solve it, I’d be glad to welcome any help.
Cheers.
