Nextcloud talk behind pengolin doesnt work with mobile network

Hello I have installed nextcloud on truenas server. I configurated nextcloud behind pangolin tunneling. I am redirecting domain to tunnel via port 30027. Nexcloud works flawlessly with this configuration but talk has problems.

I can send messages either on local network or on cellular but not video or notifications. They only work if the devices connected to wifi. I could not be able to try the devices out of the server connected network. So, I connect the devices to same network with the server via wifi it works like a charm. When I switch to mobile data one of the device, that device, becomes unavaliable via video chat.

I could find managing my problem. I feel like it is a bit ssl issue but not sure.

What Should I do to overcome this?

In general you need stun or turn to allow media connection between different networks. Both require direct internet connectivity - no chance to run behind tunnel/proxy etc..

thank you for your response. It was previously working with cloudflare tunnels but not working with pangolin.
