Purchased Two Wyze Cam v2 cameras. Both worked fine for a few weeks then one kept getting error code 0 (exit app, power cycle, reboot router). After doing this many times no change. Camera one works fine, camera two works fine for a few hours then error code 0. Very frustrating.
Might be a camera gone bad. You should contact support. See this:

If you submit a ticket from within the app, then logs will be sent which might help diagnose.
