How do I install HTTPS Certificate on 12.8.3.1 On Premise ?

[nicolas_lesaint]

I have made the CSR and get certificate from Digicert.

I have concatenate the key and cert but nothing happen when I try to add this HTTPS certificate.

When you say nothing happened, do you mean the GUI didn't respond when you tried to save the cert, or that the cert seemed to take but did not seem to be in use?
