I have installed cura 4 and octoprint 1.3.11.
Printing via octoprint is working OK
I am using a Pi camera that works OK on the octoprint screen
but I can not receive camera information in cura 4 monitor.
All worked OK with cura 3.4.
Check your Cura settings for the camera (within the printer profile setup, presumably).
Are you using a Cura plugin at all? If so, you might mention this and indicate the version of same.
And you checked your printer profile within Cura for the camera URL, right?
Thankyou, All is working OK.
