Modded server stops upon starting

Bkajnl · May 5th 2018

Hi everyone, for a year or two now I've been playing a private galacticraft server with a friend on 1.11.2, but today when I installed the 1.12.2 version my world crashes and stops immediately after the server starts. Included is a log file if it's any help:

Please try to enter /fml confirm as soon as the Vanilla freeze snapshot created message appears.

Maybe you have to enter that multiple times

Bkajnl · May 9th 2018

Sorry I took a while to get back to you, yes, that did indeed work. Unfortunately me and my friend keep lagging of the world a few moments after joining. This has also been happening with the creative galacticraft server we've been playing while I get our survival one fixed.

Roman · May 9th 2018

This could probably be a client side problem or a problem with the modpack itself.

Are your graphics settings okay?

Bkajnl · May 27th 2018

After changing my graphics settings that did indeed fix it. Now though, the problem has come back. It's the dreaded java.IO.IOException: An existing connection was forcibly closed by the remote host. Yet again, sorry for taking so long, but only now has the problem came back.

Do you have the same problem on vanilla servers?
