Server keeps crashing but I cant understand the issue.

My server keep crashing but I can't figure out whats the issue and how to fix it, I'm a bit new to making servers could someone help me out?

Here's the crash log: https://mclo.gs/3JaH3qC

Thank you! The server isn't crashing anymore but when I try to connect to it, it says I'm "fatally missing registry items." What does this mean?

Double check that the installed mods on the client and on the server are the same and that also versions of the mods are the same.

If everything is correct share the server log again and share also the client log

Thank you! I checked and made sure all mods were the same version, but I'm still experiencing this issue.

Here is my server log: https://mclo.gs/KiEC3aC

I can't seem to figure out how to add the client log, when I try to attach it to this message it says file extension is invalid.

Thank you for your help!

Paste it on https://mclo.gs/ and share the link

Sorry, but where can I find my Client logs?

Quote from Roman

in the logs directory of your local .minecraft installation.

By default &appdata&/.minecraft/logs

https://mclo.gs/MHMbIOe Here it is.

Installed mods are different on the client and on the server: https://mclo.gs/MHMbIOe#L912

If you still get that issue after you fixed the installed mods share client and server log again

I went through the downloaded mods for the server and on my computer and can't seem to find the difference. From what I'm looking at it all looks normal, are you able to see which mod is different?

The server doesn't have otg core and neat

I downloaded neat, but I have no desire to have otg on the server. Is it possible to remove it from my client?

Quote from Julian

Just delete it from the mods folder on your pc and restart the game

I deleted OTG core and downloaded neat but it's still saying fatally missing registry, is there anything else I can do?
