The server does not start after entering the atrium

In the first world, we tried to kill Ancient Fuelweaver, but it didn't work out and decided to postpone this case for now. As a result, we haven't been able to access this server for six months now. We created a new server, played for several months, recently went back to the atrium, killed Ancient Fuelweaver, returned to the base and finished playing. As a result, the message "Failed to join. Something went wrong during the connection. Try again." pops up. We have already added Windows antivirus to the whitelists (although no threats popped up), we launched mods on behalf of the administrator, but nothing. If anything, we're playing with Zapret.
