Unable to connect facebook live using the RTMP protocol


We are using MAX HD4 for live streaming to Facebook. After everything is configured in the application, it shows the error immediately when we press the button for streaming.
There is no problem when we connect the Macbook to another WiFi or even tethering from another IPhone or Android phone.
Our 4G LTE providers locate private IP addresses as the WAN IPs in the HD4. Is there any solution to this problem? Thank you.

  1. How many WAN links you have? If more than 1, please enforce the traffic for your laptop to a WAN (e.g. WAN1) only. Below is the configuration. If problem persists, please remain this setting and proceed to step 2.


  1. Have you enable MediaFast caching (Advanced > MediaFast > MediaFast and Secure Content Caching)? If so, just disable them. This allowed us to narrow down the problem.

Thank you.

Disabling of MediaFast caching solved the problem. Than you.
