Replace certificate for webUI with locally trusted cert

I’m requesting help to replace the auto-generated certificate in TrueNAS SCALE with one generated by my already trusted certificate authority. I have imported the new cert, but have not found a WebUI way to select the certificate for the webUI.

I’ve read through a number of distantly related posts, but none thus far explain how to set the webUI certificate.

Is there a place in the webUI where I can assign the cert? -or-
is there documentation that I’m missing? -or-
is there a post that I haven’t yet found?

Did you import both the certificate and the private key? If yes, navigate to System Settings > General > GUI - click on “Settings” and pick the certificate.

Settings → General
