Thank you for reporting this to us, we are aware of players encountering these issues and this is something we are looking into.

For the moment please see the steps below, as these can help to resolve the issue for users.

Verify that your network configuration isn’t blocking access to the following ports
  • TCP: 80, 443
  • UDP: 3478-3479, 6250, 12000-64000
Please also verify that SIP ALG is disabled on your home router

Some ISPs block all SIP-based VoIP traffic, including many ISPs in the Middle East. You might be able to work with your ISP to allow SIP-based traffic, or you may be able to use a VPN to connect to the service

Thank you
