It’s all broken now.
I swapped 3/8 cameras to T-P Link Tapo, 2k streaming RTSP locally very smooth, way better than this Wyze Bridge, laggy and hasn’t been working for weeks!
Check the github link above to see when it’s fixed, hopefully soon.
That would explain it! I guess I’m glad it wasn’t me, but that stinks. Thanks. I’ve been hearing more and more people say to avoid Wyze for any integration (other than Alexa). I have 18 Wyze cams. 
I want to link a potentially relevant post for those who might not be following a related topic:
I’ve also been impressed with the TP-Link Tapo cameras I’ve tried (C120 and C121). I’ve played with the RTSP just a little (streaming it into VLC) and haven’t done a lot of automations with it aside from using the free pet detection to trigger a few things, but I think they provide a competitive value that I hope compels Wyze to continue to innovate.
Same here. Got 3 recently (2ptz) and the rtsp support is fantastic. Can block internet access and use with frigate / HA flawlessly.
Probably replacing the rest of my wyze cameras soon with these tapo RTSP. They were on sale recently for 15-25$
