Octoprint site certificate not trusted?

What is the problem?

When I click onto octopi/local to use my printer I get a browser warning that the certificate is not trusted. Is this a problem? Does this mean I'm at risk for someone gaining access to my PC through the printer?

What did you already try to solve it?

I don't know how to solve it

Have you tried running in safe mode?


Did running in safe mode solve the problem?


Systeminfo Bundle

You can download this in OctoPrint's System Information dialog ... no bundle, no support!)


Additional information about your setup

OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ... as much data as possible


No, that warning looks frightening but if you click into details you will find that the reason for that "not trusted" is that the certificate is self signed. The reason to that fat warning in front of self signed certificates even in the range of private IP addresses is debatable, it does not mean that the connection is less secure encryption-wise.

Most people would use http instead of https to access OctoPrint, or to get rid of that warning you can import the self-signed certificate onto your device so that it becomes 'trusted'.
