Add the latest.log from your logs-folder after this disconnect

Add the new log or crash-report

Make a test without wythers overhaul - looks like some kind of conflict with blueprint

The following mods have version differences that were not resolved: controlling (version 10.0+7 -> MISSING) forge (version 43.3.2 -> 43.3.7) libraryferret (version 4.0.0 -> MISSING) tlskincape (version 1.30 -> MISSING) Things may not work well. Do not use the tlauncher - this is a cracked Launcher These are not supported here

Error loading registry data: Spacing has to be larger than separation Same issue - I have no idea what this refers to Maybe it's a problem with Forge directly, or there's a broken config file or something similar

Add the new crash-report/log

Yes - but from the server world, backup the playerdata folder Copy the singleplayer world into the server and join it - if this works, overwrite the backup playerdata folder with the one in your server world

Did you test it with a new world? Also change the RAM allocation from -Xmx2048M to -Xmx4G

Also remove [1.12.2]-Epic-Knights-Armor-and-Weapons-6.2v(uncomplete).jar

Maybe an issue with performant or theabyss

Check the mods folder for musictriggers-1.12.2-5.3.jar Looks like this file is twice available - remove one

Start roaming around this world and visit your areas - then upload this world to the server

Yes - with tools like FileZilla (via FTB-Access), you can upload/download files from the server

If you are using AMD/ATI, go to their website and download/install the latest driver build If there is no change, or you are not using AMD, add the full crash-report with sites like https://paste.ee/ and paste the link to it here

Make a test without scalinghealth

You are not logged in In your Launcher, log out and back in Make a test with disabled firewall and anti-virus program Or a test with another Launcher like MultiMC, AT Launcher or Technic Launcher

Add the log from MultiMC - maybe there are some more information

Start without any mods - if this works, add these one by one or in groups

Maybe a mod adding/changing biomes - I have no idea

And without railways/Create Steam and Rails?

And without modernfix?

Make a test without NoChatReports

Remove wildwestgunsd - looks like it is a client-side-only mod

Replace it with this build: https://www.curseforge.com/minecraft/mc-mods/endofherobrine/files/4468174
