Failed to authenticate error (gg.playit.control.ChannelSetup)

I’m not sure what to do about this error I keep getting. I’m running the agent through the plugin “unofficial playit-gg mod for fabric 1.20.4”
Running the “official plugin” through bukkit did not work as well. Same error.

In the game, if I run the command “/playit agent status” it says connected.
It seems to find the tunnel correctly, then it gives me this:

Apr 14, 2024 5:02:55 PM gg.playit.control.ChannelSetup$FindSuitableChannel findChannel
WARNING: Got IO error working with :control.playit.gg/2602:fbaf:814:0:0:0:0:1, error : java.net.SocketException: Network is unreachable

Then after a while it gives me this:

Please, any help or insight would be much appreciated! Thank you. edit: changed category and title

SOLUTION (for those who are incompetent, like I am)
Don’t use the plugin and the app at the same time.
Use the app by itself.

Also, to get it running 24/7 on linux, follow this guide: How to run playit 24/7 on Linux | playit.gg - support pages

Thanks to nonamen_ for all the help.
