Re: error while logging in

Please try to clear your DNS cache and reboot your Internet  https://help.ea.com/en-us/help/pc/how-to-flush-dns-cache-for-windows/ 

Also, if you have an Antivirus, then please turn off it and turn off your Windows firewall

If the issue still persist, then try to edit your "Hosts' file. Please check this video https://www.youtube.com/watch?v=Rf3FQJo0ugQ&feature=youtu.be
