Tapo TC55 (C720) floodlight camera has problems with multiple ONVIF connections
Hello,
I have a Tapo TC55 floodlight camera (same as the Tapo C720 as far as I can tell) that seems to hang/stop functioning randomly. It remains connected to wifi and will respond to network pings, but it won't allow any connections (RTSP, ONVIF, etc), doesn't show up in the Tapo app, and doesn't turn on the floodlight in response to motion. The only way to get it out of this state is to cut power to it, wait a few seconds, and then power it back up; at that point it comes back online and everything works correctly.
This has happened twice in the past week. I don't know what is causing it, but I saw a theory in a review I found on the Best Buy product page (search for "reboot" in the reviews if that link doesn't work) that it could be due to cold or rain. It is slightly cold (40s - 50s F) and a bit rainy (0.5" today) here, so both of those are possibilities. I installed a gasket behind the mount when I put the camera up, so I don't think any rain is getting into the enclosure (plus nothing is shorting and it works perfect after it is restarted).
Update: see follow-up post below.
It's not a wifi signal problem - the app shows it has 3/3 bars of signal, it remains connected when it freezes, and it starts working immediately after rebooting.
Has anyone else experienced this?
