When testing on production, I’m seeing my server side video producer transport frequently change state and tuples. Listening to the transport icestatechange and iceselectedtuplechange events, a lot of the time I see behavior like this in the logs: 2020-08-18T15:06:34.371-07:00 Client f7113813-6462-…

Just network issues coming to my mind (given that it just happens in your deployment). Try with just UDP and just TCP and see how it behaves. [image] whather: Is this normal behavior? It’s not. [image] whather: And if so, when should I be calling restartIce on the transport? No, you …

Thanks for the reply. Ok trying just with UDP fails entirely. The transport never fully gets connected, just stays in connecting. Trying with just TCP works flawlessly. So sounds like I need to flip another switch in our server network to make UDP work. We do have UDP ports 40000 - 49999 open, but …

I’d say that your server receives UDP packets but cannot send UDP replies. Firewall stuff probably.

I was having the same problem as ghempton and whather. ICE selected tuples would oscillate back and forth between udp and tcp. I’m also running on ECS/Fargate/Alphine-Linux. Switching from node:14-alpine to just node:14 seemed to resolve the issue for me.

This was ultimately determined to be caused by the same issue here: Using Chromium in a Docker container to connect to mediasoup in another container fails (with mediasoup >=3.5.8).
