The problem is not in modifications, everything works in singleplayer, the problem is on the server side. Perhaps you could help me?
I managed to find out that the problem is not in the world files, not in the mods and not in the plugins. I'm honestly running out of ideas for this.

Should probably list the mods the server is using
Is it your server?

Stuff like this could limit what a normal player is allowed to do

no, I don't have this plugin on the server. I don't think a mod list is necessary, because I've found out for sure that the problem is NOT mods or plugins. I think I have problem with anything alse

Yeah, no way is anyone able to help you if you can't even be bothered to provide any basic information
Thousands of mods available, different server providers with their own custom setup etc. and you give no context

Good luck
