My setup:

3 new CX820 cameras (with 128gb microSD cards each), which are connected directly to the Reolink PoE switch (RLA-PS1).The PoE switch is connected directly to the Starlink Gen 3 router, and is getting constant internet feed, whole network runs without issues.

Problem:
Everything works perfectly for a few days – I can access the cameras remotely via Reolink app, they record motion which I can replay, I get push notifications, and so on. And then after a few days, they just randomly disconnect. Reolink app says "Device disconnected" for each camera, and I can't access them.
Interestingly enough, I'm still getting push notifications via Reolink app about events, even though I can't access them via the same app – as mentioned, they're shown as disconnected.

Turning off power to the PoE switch and back on fixed the issue initially, but then it happened again after a few days. Obviously this sucks, because the cameras are at a remote location, and I can't drive 200km back and forth just to fix this issue repeatedly every few days.

Please help!
