We have a Konica Minolta bizhub C224e and this printer is our main printer for our company.
I am trying to import a certificate that allows a secure connection via custom domain name.

whenever i try to import the certificate which is in .pfx format i get an error message saying file format error.
i tried renaming the format to .p12 sadly i still get the same error.

What am i doing wrong?
Does this printer still support certificates from lets encrypt?
