The Bugbug bot thinks this bug should belong to the 'Core::WebRTC: Networking' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Cindy, would you mind attaching a copy of about:webrtc. There is a save button at the top of the page. This will help us narrow down what is happening.

I'm seeing this in the logging in a number of places:

"(generic/ERR) NrTcpSocket::OnClose 23743e54c00 reason=2152400251 name=NS_ERROR_PROXY_FORBIDDEN "

The proxy you're trying to use is probably responding with a 403. You could verify this using wireshark if the proxy is not using SSL, I suppose.

After use Cisco common Proxy address to do proxy, this issue does not happen, so maybe proxy server setting issue. now close this issue
