Sorry for the delayed response,

Please check if ports **6001** and **8089** are open on any active firewalls. Also, have you installed a valid SSL certificate?

Additionally, you can update to the latest version of VitXi: [VitXi WebRTC 4.1.0.0 Update](https://forums.vitalpbx.org/t/vitxi-webrtc-4-1-0-0-update-available/4214).
