Problem with deployment in Google Cloud Run

[fraviofii]

I'm trying to deploy a webrtc server based on the server sample.

I integrated with gunicorn, created the dockerfile and deployed successfully on the Google Cloud Run.

The web page is loaded. But when I press the start button, the connection between the browser and the server is not established.

Here is the logs that I could get from console log:

The ICE connection could not be established. Testing locally everything works fine.

I am new on WebRTC and I don't know how exactly how to address this issue. What am I doing wrong?

[fraviofii]

The problem here is that Cloud Run cannot start a connection with outside servers. That's the reason that is does not work.

I don't think it is possible to deploy on Cloud Run.

Maybe it's a problem with the firewall setting on Google Cloud. By default it blocks nearly everything. (I planed to deploy on Google Cloud too.)
