Can anyone explain me how Minecraft sessions/login servers work? What packets to what ports do I need to whitelist for it? I set up my tunnel with the vps, but when I try to connect to the server it says: "Failed to connect to the server Error occurred while contacting login servers, are they down?" And on bungeecord console: [SEVERE] Error authenticating <myname> with minecraft.net io.netty.handler.timeout.ReadTimeoutException I made my server offline mode just to test, and I successfuly joined it, so something is definitely not letting contact login servers or establish a session. HELP!
