Hello, I tried a few servers at random to test, and was able to login to servers. That being said, it is likely that you are having issues connecting to these servers, which is possibly not of any fault of your own. I would suggest clearing client cache, flushing DNS cache, then restarting your PC to see if you still experience these issues. If you do, most likely you will need to login while using a VPN, which will likely require most if not all of the available servers. If this is not an option for you, you might need to contact your ISP and ask them to test the connection and see if there is anything they can do to correct the issue.
