It's very necessary to fix this, but I do not know how( I lose online due to this error.

People are most likely crashing from some shitty addon you have. You should contact one of those people for more details, such as crash logs.

There was no such error, I did not touch the server for several days and suddenly it appeared.

[joeyjumper]

are you using addons from the steam workshop? one of them could've updated to cause them to do that.

[Findes]

Do it? In what sense. Yes, I use.
