This usually means a connection cannot be established to our login realms. Possible causes:

Your firewall is blocking connections, deactivate it.

You are behind a router and your ports are blocked. Easiest way do avoid this is set your computer as a DMZ zone (demilitarized zone). How to do this depends on your router, google enable DMZ YOUR_ROUTER_NAME. If you can't do that but you know how to unblock ports, check the next step.

If you are in a public network with ports blocked and no access to the router you will have to contact your network administrator and tell him tu unblock the following TCP ports: 1111-1119, 1129, 8001-8009, 8019, 8085, 8086.
