No one can join my Forge server - 1.20.1

[Vizor]

Hi, I've made a server on Google Cloud Platform using Forge machine and Minecraft version 1.20.1.

I'm using my own created modpack. 

Server is running, but no one can join it. We are getting screen error "internal server error".

My latest log: https://pastebin.com/xbRiEv16

 

Could it be problem with ticking?

Or some of the mods are causing this?

How can I solve this issue?

Referring to the crash, the server is down due to client-side-only mods

Remove fpsboostremake from your server

 

If this is still not working, add the new log - maybe there are some more client mods
