Cooldown For not so my reasons

Hello
I got Vac Authinticator Error out of nowhere and while fixing that i got cooldown for 12hrs.
And when i fixed it and tried to connect the server it showed that already someone has entered the server.
Can you guys help me with this cooldown. As i had no other intentions of leaving the server and getting cooldown for not of my fault
