In Windows, you can export a certificate with the private key and the certificate chain into a PKCS file, which is what UTM needs. If you cannot do this, you will have to construct one yourself.
Download the OpenSSL kit. The OpenSSL website provides only source code, but has links to other sites that provide pre-built install kits to use at your own risk.
This command should convert a PKCS#12 format-file to a PEM (PKCS #7 text) file
<path1>\openssl pkcs12 -in <path2>\<filename>.pfx -out c:\temp\<filename>.pem -nodes
Append all the .pem files into a single text file using your favorite text editor.
Then use this command to covert it back to PKCS#12 format.
<path1>\openssl pkcs12 -export -in <path2>\<filename>.pem -out <filename>_2.pfx
Then you can load the certificate chain into UTM.
I just updated my previous post to generalize it a little bit more.
Openssl is available for lots of platforms.
There may be a simple solution for Linux which does not use OpenSSL, but I cannot help in that respect.
