3cx Post Linux install - Certificate file

[BM-NZ]

Hi all.
With 3CX v20, once I upload the confiuration file (from the system registration), the next screen popping up states:
Please select the path to your Certificate file (.pem, .crt or .pfx only).
I'll be using 3CX and haven't even started the process in Linux to generate a certificate file.
It also is something new compared to post Step 4 on the installation manual.
Any ideas on how I can get around it?

Do you try to use an own fqdn or 3cx? If you use an own fqdn this is normal.

I used our own FQDN.

Than you need an certificate for this fqdn.
