Can't contact license server

Hey,

apparently the license server got moved to another IP address but now if I try to connect it says ‘Can’t contact license server’ or something like that.

I even deinstalled and reinstalled it and it still didn’t work. Furthermore it still showed me the same IP address and Port even though I reinstalled it so I think some data wasn’t deleted when I deinstalled it. Maybe removing them and creating them again would work?

Anyone know what to do?

Edit:
They deactivated the firewall and now it works
