The Tapo C530WS goes offline after around 1 day with the following log:

<4>2025-09-24 19:36:12[tpssl][115904.009]domain: euw1xxxxxxxcom DNS failed, error_type: 1006. ( I had to remove the exact address. )

<2>2025-09-24 19:36:12[CloudIot]MQTT conn err: 1006.

<2>2025-09-24 19:36:12[CloudIot]MQTT event 4 err, stas 0

<4>2025-09-24 19:36:22[tpssl][115914.010]domain:euw1xxxxxxxcom idle --> dns query.

This message repeats over and over again, after finally the camera goes offline. The diagnostic file btw is corrupt, it contains lots of non-ASCII characters at the end, blows up to 5 MB.

Firmware is the latest, camera is connected via LAN, DNS servers were set to 1.1.1.1 and 8.8.8.8 but that didn't help. After a restart the cam works great, but for just around 24 hours...

What's wrong?
