I’m experiencing an issue where my network is preventing the keyframes for my webrtc/mediasoup livestream from being decoded. Using the same device and browser, if I switch networks the livestream plays as expected.

Normally you would think it’s a firewall or port issue, but the ICE lite connection is successful and the client is receiving video data and keyframe requests, the single point of contention seems to be the decoding of the keyframes.

What network specific issue could be causing this to happen? Does anyone have suggestions to debug this further?

MTU size / fragmentation? What does "the client is receiving video data and keyframe requests" mean? Delta frames arrive, but not key ones? Key frame requests come from the client, and it's a different transport. I'd take a look at RTP traffic arriving on the client with WireShark to see what's wrong

MTU size of the keyframe packets is very likely the issue. I will test with wireshark to confirm.
