Cannot access the server due to Fatal error

Hi all,

I have been trying to get on my server for the past couple of days and every time i try to get on it says “A fatal error has occurred, this connection is terminated”

My friends can access the server with the same mods and same mod versions so i do not understand what is wrong. My single player worlds won’t load up but i’m not sure if that’s related or not

I cannot find any help online so i was wondering if someone has a solution

Here is the server log:

Forge server log [#XknmWUG] - mclo.gs

Any help would be appreciated

There is the client log, i am going to have a look through it to see if I can see anything but if you could let me know what you find that would be appreciated

Edit: I have found out that the mod Custom Mob Spawner is what is causing the error, is there any way for me to fix it, installing the mod again did not help

Try deleting the config folder. It can be found in the .minecraft folder in your pc.

I tried that in the end, it worked which was really good

thanks for your help
