strange problem using home wifi connection and mobile data

I would like to use Unity Render Streaming 3.01, and I find myself in this configuration:
CASE1:
- server pc : using Web Browser Input Sample connected to my home wifi
- client: android app that connects to the server.
- smartphone samsung S10 lite android 11

test1: smartphone connected to home wifi--> everything works

test2: smartphone connected to mobile data 4G --> not working

CASE2:
- server pc : using Web Browser Input Sample connected to my home wifi
- client: android app connecting to the server.
- smartphone XIAOMI MI NOTE 10 lite android 11

test1: smartphone connected to home wifi--> everything works

test2: smartphone connected to mobile data 4G --> everything works

Helppppp meeeeee

 

Add new information:

1- it seems that with Android 10 streaming works fine;
2- on Android 11 this same streaming NOT working with same code

Any Idea ?

 

I have the same problem. When I am connected to the same wifi as Unity is running everything is working on my iPhone (iOS 14.6), but if I switch to mobile data, it stops working. I have tried running it first via mobile data and when I press play button there is no video and buttons are not working.. and if i switch to wifi it starts working immediately.

I have deployed web app on Heroku platform and I have custom TURN server hosting on google VM. It is a bit odd because there are no errors and I can see the info logs in unity editor even when I am connected with mobile data but there is no video displaying.

 

Thank you for pointing me in the right direction!

I have resolved the problem! The problem was with my TURN server (closed ports). When I opened ports on google cloud, I have created a new tag for "targets" and I forgot to apply that tag to my VM.

For everyone that has the same problem with no image displaying, it is probably your TURN server.
