Several Players attempting to join my locally hosted server get disconnected

[furiousk900]

After the three starting players joined the server we received issues with new people joining, where it disconnects them and says "Internal Exception: java.net.SocketException: Connection reset".

They appear to connect to the server, then move around and try interacting with blocks, items, etc until they are disconnected from the server and receive the aforementioned "Connection Lost" screen.

Below I have posted the server log files and two of the external players' log files when they tried joining the server numerous times.

Player 1 Logs

Player 2 Logs

Server Logs

I'm not sure why it continues to disconnect them, whether it's a mod confliction, clientside internet issue, or serverside issue overall, but we've attempted troubleshooting to no avail. Any help would be much appreciated

Looks to me like they are taking too long to connect?

There is a 30 second timeout when connecting to a minecraft server.

The times on those logs don't match on the client/server logs, but one example is:

As you can see it is taking longer than 30 seconds to connect. This client is taking 25 seconds just to synchronize the registry information with the server.

 

A mod like this one might help?

Seems to have worked so far with one of my players, will see if it continues to do the job. Thanks for the help!

[furiousk900]

Even with the additional mod two of my players seem to be receiving the same error message. The server console says nothing different other than "Timed out" when they leave the game, other than for Player 2 which was able to connect somehow after several tries though was disconnected ~10 minutes later and was unable to reconnect.

The first log shows the client is losing its connection. I can't see the reason in that log.

It's not due to initial connection timeout. e.g. in the last one it is 30 seconds after the player notionally joined the game.

The second log seems to be an due to an error? Just before the player is disconnected they are getting a message about invalid data.

For the first problem, you need somebody who can help you understand why that player is losing its network connection. It's not me 🙂

I would guess it is related to that player's computer struggling to keep up with running the game given how long it takes to make the initial connection (70 to 90 seconds)?

 

The second problem looks to be a bug in a mod or maybe some mismatch in what the client has installed/configured versus the server.

There are warnings from journey map at the same time about missing textures related to entities which might give a clue to which is the problem mod?

I would suggest to start with getting that user to reinstall the modpack to make sure they have the right mods, versions, etc.

[furiousk900]

I'll do some testing with the files then and hopefully get it working, they aren't on often so it might be a little while until I figure if that works or not, but thanks for the suggestions!
