Logitech C920 - Can't get video output anymore

[proven flare]

Hardware
Wyse 3040, Ender 3 V2, Logitech C920
Software
Debian Bullseye, latest crowsnest installed.

I had this exact set up working a few months ago, until a mechanical failure took the printer offline for a while. Once I fixed the mechanical aspects & set everything up again, had to do some updates & Crowsnest was the only thing that hasn't worked since.
I've uninstalled completely & reinstalled using KIAUH, switched between MJPEG-Streamer, Adaptive MJPEG-Streamer & WebRTC (camera-streamer), but none of them work. Looked at the debug logs & can't identify any issue with the camera (which works on other devices)

Attaching my logs in the hope that someone smarter than me can point out where I've gone wrong.

Set no_proxy: true

If that doesn't work, send a screenshot of the settings in Mainsail

Tried it with no_proxy: true, still no luck

Settings of the cam in Mainsail

Not the config in the Mainsail editor 🙈

I, uhhh, knew that... Was just testing you, obviously 😄

Here are information about the ports and the according url

You changed your port to 8090, so /webcam/... won't work for it

So change it to the full address: http://<ip.of.your.pi>:8090/?action=stream and http://<ip.of.your.pi>:8090/?action=snapshot

Other option would be to just use 8080 again in crowsnest
