Turn off your firewall/ antivirus:

Antivirus and firewall applications on our computers act as a defence barrier when connected to a network. It blocks out specific services and applications that it does not see fit. There is a chance that your firewall blocks your game’s access to the servers. So turn off your antivirus and windows defender entirely and check whether that resolves your issue.
