Thank you Charlie for the solution. I was editing while you replied... Thanks again.
*We can not see the camera stream on the OctoPrint website at octopi.local.
Curl http://octopi.local:8080/ fails to connect local port 8080 connection refused.
Curl http://192.168.1.53:8080/ fails with the same message.
Curl http://127.0.0,1:8080/ returns an mjpg_streamer test page
Camera model*
We are using an Element 14 Raspberry Pi Camera V2 with Pi Model 3 B.
What is the problem?
We installed Octopi V 0.18.0 and updated and fixed broken and rebooted many times.
We can't see the camera on octopi.local:8080/?action=stream with Firefox nor Chrome on Fedora 33.
We are able to ssh into octopi.local, raspi-config pi camera is enabled.
Verified that webcamd is running.
It looks to me like we do not have permision to open port 8080 on octopi.local?
Here is the error message on OcotPrint local webpage.
Webcam stream not loaded
It might not be configured correctly or require authentication. You can change the URL of the stream under "Settings" > "Webcam & Timelapse" > "Webcam" > "Stream URL". If you don't have a webcam you can also just disable webcam support there.
Currently configured stream URL: http://octopi.local:8080/?action=stream

What did you already try to solve it?
sudo apt-get update
reboot
reboot...
sudo iptables -L
sudo iptables --list-rules
both return no rules.
Tried following examples online then realized that mjpeg-streamer already exists in octopi and there was no need to try and reinstall it. Also realized that running mjpeg-streamer again just created another one running. Rebooted many times...
Verified that the mjpeg streamer service was running many times.
stopped webcamd
verified v4l2-ctl --all shows the pi camera on video 0.
verified that raspistill -o cam.jpg writes the image cam.jpg which looked fine. (Note to do this we had to enable raspicam in /boot/config.txt). Just enabling the camera using raspi-config did not work? Did not install a desktop nor any other applications. Used scp to copy the image to my main computer.

- It seems that you don't have VL805 (Raspberry Pi 4).
There should be no problems with USB (a.k.a. select() timeout)
