Hello everyone,
best wishes for 2026, for me started with Problems in openhab :-(
after updating to version 5.1, I'm getting the following error message from my Instar cameras:

Camera at IP:xx.xx.xx.xx gave a reply with a response code of :404

The cameras are recognized by the network, but I can no longer send commands or access a live feed. Please help me.

I cannot access the video stream of my netatmo cameras since OH5.1 too.
The issue in github is this:
