SSL Lets Encrypt (another Q)

Hey guys, seem a few post about this error and have tried 90% of them with no success. I have another spanner to toss in, I have a Kemp reverse proxy in the mix as well, but all seems to be fine. I can point my browser to the URL (apache(dot)portfoxdevelopment(dot)com) and it resolves.
I’m on Webmin, not sure if that is a different issue than on Virtuamin?
sorry about the (dot)'s cant put more than 2 links in a new post

Thanks in advance

Here is the error;

Virtual server running on ESXi 7

Webmin version: 1.981
Virtualmin version: REQUIRED
Related products version: RECOMMENDED

Webmin is just the ‘global’ server scope config section, Virtualmin is the per-server configuration section.

You’re attempting to request a cert through Webmin Configuration > SSL Encryption, or for a virtual domain through the Virtualmin tab? You might be hitting the wrong virtualhost - or Webmin’s backend server may be creating the ACME response file but it’s not being served due to a quirk of your reverse proxy.

Is a virtual domain or the primary hostname for the server?
