I am the Server owner, as i try to run the Server from my own PC. I set up the Server with the Direwolf20 pack Version 1.12.0.
As this Server is a fresh install from 2hours ago I dont think reinstalling changes the outcome. 

Debug.log can be found here:

Same Errror diffrent log: 

https://we.tl/t-7PIRUb6IVn

 

Just installed the newest version of forge, error still persists.

I dont get a newer version of the log though. Otherwise I would have linked it. 
So:
- Server starts
- Player connects
- Error
- Player disconenects

The debug log of the server does not update --> i still have a log from 23:03 CET

I now include the latest logs

explination

I seem to be completly dumb at the moment... My mods folder is stacked full, how would i even start vanilla?

let`s try again... i am so incredibly sorry...

 

I went to the FTB App, downloaded the direwolf20 pack version 1.12.0 and gave it a go.

First error: not correct forge version

Downloaded the latest forge version, copy pasted forge version into direwolf20 pack

here i am. seemingly nothing works. I will try a complete reinstall next.

This is the error I get when I completly reinstall the pack and change nothing

I downloaded the latest beta version of the direwolf20 pack, and it had a new forge version with it. 

I tried starting the beta variant but there is a bug;

So, my naive brain told me lets try just copy pasting the new forge file it into the old folder, i even rememberd to change the path of the start.bat to the new forge.jar

If I want to choose the install server option and then navigate  to the path provided by the direwolf modpack  it says "There are already files at the target directory"

After choosing to ignor this warning and letting it install over the old dir

I only see it using the newer Version, could you explain where you can see that the old version is used

 

you use the recommended version of Forge,
but you should use the latest version (1.16.5 - 36.2.26)
