Opponent Video is not showing when connected to the VPN in both devices

[sapkotamadhusudan]

Hi, I'm using the ConnectyCube SDK to develop the communication application and i'm using my office VPN connection to work remotely. But when i try to work with ConnectyCube Video calling feature with VPN connection, opponent video is not loaded.

I've tried using this sample (RNVideoChat) and the issue still occurs. I've attached the logs of both of my device using this sample application (RNVideoChat).

In general - we do not have any VPN related restrictions, probably it's =more about some blocked ports etc

Could you please do couple tests for us about connectivity environment, this will help us analyze the situation

@DaveLomber i've followed your instruction on my mobile device with VPN connectivity on. And the results are:

Thanks for the reports provided

So seems ICE candidates can be gathered (which is also confirmed by logs provided)

But then, by some reason, ICE connection is failed when it tried to connect each other:

One more check please - does https://appr.tc work at your env?

[sapkotamadhusudan]

@DaveLomber Yes, https://appr.tc/ works at my env. And one more thing to add (idk it would be helpful or not). i did also tested the android-messenger-app from sample, It works while my VPN is on.
