Problems with webcam and HAProxy

Open JargoV opened this issue 2 years ago • 4 comments

I can't manage my camera "Logitech C170" to run on OPi PC


pi@citrico-opipc:~$ systemctl status webcamd.service
● webcamd.service - the OctoPi webcam daemon with the user specified config

pi@citrico-opipc:~$ sudo journalctl -u webcamd.service

I need to start manually the webcamd.service even it is enabled in scripts/citrico-config But i still have error "Webcam stream not loaded" LED on webcam isn't lit

Also i can't establish connection with Octoprint on web browser without typing port 5000 because the HAProxy won't work:
