Foscam, no connection after power failure

I’m using the Foscam integration to view my IP camera’s. I had then all (4) up and running, but after a power failure, one of them no longer connects.
I tried removing the entity but now when i try to add it, i always get the msg ‘Cannot connect to host’.
My other camera’s, one is identical, are still working.
Also in VLC i can view the rtsp stream without any issues.

I also tried to add it as a mjpeg camera, but no luck.

It almost looks like HA can’t connect to that specific IP.

Anybody have any idea? Because i’m running out…
