**Summary**  
Error: unable to connect to the voice call: timed out waiting for peer connection.

I installed Mattermost, Nginx, Postgresql13 on a VM that is in private network and has internet access through NAT. Another VM in the same private network with Nginx proxy is configured as server [msg.domain.com](http://msg.domain.com) accessible from the Internet.  
Chats are working fine but calls not. Call between 2 nodes can not be established and error shown on the Android app “Error: unable to connect to the voice call: timed out waiting for peer connection.”

How can i fix this?

Check [Calls self-hosted deployment - Mattermost documentation](https://docs.mattermost.com/configure/calls-deployment.html) especially [Calls self-hosted deployment - Mattermost documentation](https://docs.mattermost.com/configure/calls-deployment.html#troubleshooting) Calls requires 8443/UDP bidirectional

I checked the documentation prior posting.  
Could be something wring with port 8443 in one direction.  
In nc on client i send text and it is well received on mattermost host. Sending from mattermost host to client disconnects the nc.

This is the topology:

I tested call from Desktop client to Android client and watched the tcpdump of port 8443.  
NGINX VM - no packets.

ICE Host Override is set to [msg.domain.com](http://msg.domain.com) which points to the NGINX proxy.  
Why no packets are received on NGINX proxy port 8443?

What are the IPs 192.168.248.1 and 192.168.91.1 ?  
I do not recognize them.
