Let's Encrypt certificate for Virtualmin host itself? [SOLVED]

This might do the trick:

  1. create a virtual server with the hostname of the Virtualmin server
  2. apply a SSL certificate
  3. access Virtualmin on port 10000 of the hostname

Or don’t do 1 through 3 and access Virtualmin on port 10000 of any domain that is currently hosted on that server.
