First outbound stream on WebRTC connection server side times out consistently

[mxinden]

Summary

Using libp2p/universal-connectivity#3, the first outbound substream always timeouts. When using libp2p-gossipsub as the first NetworkBehaviour that outbound substream drops the subscribe message to the remote.

[2023-03-27T18:00:16Z DEBUG libp2p_gossipsub::handler] Dial upgrade error: Protocol negotiation timeout.

Possible Solution

Version

Still need to write a reproducer. Posting here anyways for tracking purposes.

One can build a reproducer on top of libp2p/universal-connectivity@a8c18c8.

Hacky solution for now is to retry on outbound substream dial upgrade error.

Would you like to work on fixing this bug?

Maybe

In case the bug turns out to be in webrtc and not in our code, it is going to be difficult to fix because we can't upgrade at the moment. See #3552.
