Lets encrypt "Output did not contain a PEM path!"

When requesting a certificate for a virtual server I get the following error:

Requesting a certificate for mydomain.com from Let's Encrypt .. Failed to request certificate : Output did not contain a PEM path!

How can I fix this? This has been driving me crazy for weeks.



Howdy -- what distro/version is it that you're using there?

What Webmin and Virtualmin versions are you using?

And are you using Virtualmin's built-in Let's Encrypt support, or did you configure it to use the official Let's Encrypt client?
