Pi Camera streaming problem

What is the problem?
My Pi Camers is correctly detected by my raspi Zero

pi@octopi:~ $ vcgencmd get_camera
supported=1 detected=1

BUT the control screen stay blocked at webcam stream loading screen.
Can anyone help?

What did you already try to solve it?
I tried to put the mke next to the router cause i thought it might have been a problem of connectivity.
I also tried to activate/deactivate the camera from raspi-config

Additional information about your setup (OctoPrint version, OctoPi version, printer, firmware, octoprint.log, serial.log or output on terminal tab, ...)
