What ports for partner app?

My partner app only displays partial information and I suspect that it maybe a firewall config. the KB only states “enterprise-strength firewall on either your computer or phone, it can also prevent you from connecting, so we recommend making exceptions for Zwift as appropriate.” 

Not terribly helpful without knowing which ports to open. Any ideas which port?

Hi Irvin,

Zwift Mobile Link listens on TCP port 21587. As long as you can ping your mobile device’s IP and telnet successfully to 21587 when the mobile app is running, it should connect automatically when you start riding in Zwift.
