I founded previous discussions about the error “can t login. Check internet connection” and I have tried everything. I already uninstall zwift, I tried with other laptop and I get the same problem. I downloaded zwift on my iPhone and when I am connected to WiFi I get the same problem. I already called to internet provider and the have restarted the modem to factory settings. I still get this problem. I disabled firewall but it continues with the problem. I ve read to restart laptop to factory settings and Right now I am waiting for my laptop. The curious situation is that when I access from my phone whitout WiFi I can login. Anyone has a clue on this one?
