"Internal Exception / Connection reset by peer" when joining — how do I fix it?
"Internal Exception: Connection reset by peer" is a generic network error that usually means the connection was interrupted or the server hiccuped mid-join. It's rarely fatal and often clears with a restart.
What it means
The message tells you the link between client and server dropped unexpectedly. That can be a momentary server hiccup, a mod or plugin problem, corrupted player data, or the player's own network.
How to fix it
- Restart the server from the Console and rejoin.
- Check the Console for an error printed at the moment you were dropped — often a mod/plugin or corrupted player data.
- Make sure your client version matches the server exactly.
- If it only happens for some players, it can be their network or ISP.
Tip: If it started right after adding a mod or plugin, remove that one and test — a bad addition is a frequent trigger.
Frequently asked questions
It keeps happening only to one player. That leans toward their network/ISP or a corrupted player file for their account; have them try another network.
The Console shows nothing at the drop. Restart once more and watch closely — transient resets sometimes don't log, and a clean restart clears them.
