After Core 153, Discord Cam no longer working

I can confirm that I was having the same problem, and that it only resolved after rolling back to 152. I was having a similar issue with Google Meet. (See discussion in this other thread.)

I hypothesize that there is an issue with DTLS connections in 153. I’ve taken Wireshark traces that show that DTLS connections were not completing on 153 (they get stuck after the first response from the host on the Green subnet and then start over), but do complete with 152.
