Please read [How to report problems](https://forum.vassalengine.org/t/how-to-report-problems/84989). In particular that `errorLog` content should be between ````` to make it unformatted and thus easier to read.

Only images can be attached to posts. That’s why you need to quote the `errorLog` between `````.

Note the message

```auto
Caused by: java.net.SocketException: Connection reset

```

If you look up that error, it can point to settings on the local network, or even on the remote host. However,

> Only I get disconnected — my friend, using the exact same VASSAL/Java version, stays connected fine

would indicate that the local network is likely at fault. Could be a DNS setting, router filtering, and so on.

Have you tried with a different machine (preferably a Windows 11, MacOSX, or Linux machine) on the same network? If so, what do you see?

Have you tried with the same machine on a different network?

If you do a WWW search on the above error ` java.net.SocketException: Connection reset` - you will find many suggestions as to what to do.

Could you point to the original Github issue or forum post? The most relevant post I could find was [Lost Connection to Game Server](https://forum.vassalengine.org/t/lost-connection-to-game-server/84299) from January 2025. Incidentally, this is why it is important to close resolved threads so that it is easier to find solutions to problems.

You can also try to [debug Vassal](https://forum.vassalengine.org/t/how-to-debug-vassal/90403), to see if you can pin-point the problem more specifically.

Yours,
