Voice calls impossible

Troubleshooting
1

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 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 especially Calls self-hosted deployment - Mattermost documentation 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:

Mattermost
Mattermost735×351 18.9 KB

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

ICE Host Override is set to 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.
