Whenever I try to join anyone, i get a screen that says: P2P Sig/error: code 100, sometimes it will also say Code: 102.

Whenever i try to join anyone on cross platform, I get a screen that says P2P Sig error code 102. It has stopped me from playing with friends for moths. Ive tried resolving this issue, and i ended up losing all of my worlds with no way of getting them back. Whenever someone tries to join me it just tells them its a communication issues. We all have crossplatform enabled and good Wifi also. My friends have XBox gold pass, so we know thats not the issue either.
