Pi Cam not detected by OctoPrint

What is the problem?
My Pi Cam is not detected by OctoPrint. I don't think it's detected by OctoPi either, but I'm not an expert. On the Control tab, it gives the error " Webcam stream not loaded". In Settings > Webcam & Timelapse, the test gives the broken image link graphic.

What did you already try to solve it?
Restarted OctoPrint
Restarted Raspberry Pi
Tried shorter cable
Made sure that the cable was firmly seated and clamped in the Pi Cam and Raspberry Pi
Checked a couple of videos to make sure that I had been installing the cable correctly

What about the cam led? Does it lights up red?

@Johnnie_Walker there's an LED on the camera? I didn't know that, so that's a no.

Does that mean that the camera is defective (since I have tried it with 2 cables)?

Yes. There is a red small led at the top right.

@Johnnie_Walker mine is definitely NOT on. Would you call that a defective camera then? The cables are definitely plugged in correctly.

I also went into raspi-config and made sure that the camera interface was on.

Could be a problem at one of the connectors. If you have another Pi, or some friend of yours would be easy to test.

And don’t connect or disconnect the camera with the Pi on. It’s not an USB port.

Yep, I remembered to unplug the Pi before making changes.

I totally forgot that I had another Pi. It doesn't work with that one either. OctoPi doesn't see it, no light. Guess I need a new Pi Cam.

Too bad it´s dead. I think it´s very useful, but would be nice to have a camera with a wide angle lens. Once your is dead, I would recommend you to look for one like this. I have the Pi Cam attached to my heated bed and when I print larger objects I don´t get a good timelapse.

Just rememebered something that you can look before changing the camera. Is it enabled at raspberry config?

sudo raspi-config
Choose 'Interfacing Options'
Enable the camera
reboot

Interesting. The V2 Pi Cam does not appear to have that handy, dandy LED. I even went to the company site and looked at the schematics but I cant find a diode on the schematic. That makes it hard for me to know if my formerly functioning, now non-functioning Pi Cam V2 is bad or not. Any thoughts?
