I have been using Zwift on my Lenovo Yoga and everything’s working fine. Today I wanted to try Zwift on my more powerful desktop to see how the graphics look. I am using Norton 360 for my security and firewall. After installing the Zwift app I tried to login and I get a message to check my internet connection. Both the Yoga and my desktop are using the same version of Norton 360 and I have not done anything special to either as far as the firewall is concerned (or other security for that matter). When I turn off the firewall on my desktop, the login works just fine. Since I don’t want to run with the firewall off, does anyone know if there is something I need to configure in the firewall to get the login to work while the firewall is running?
