Trying to install Virtualmin like I have done many times before. Using Centos 7 - get this Error even though I have a fully qualified domain name
Error: Failed to download utility function library. Cannot continue. Check your network connection and DNS settings.
Yes, the installer is compatible with CentOS 7, but you absolutely should not be installing on such an old distribution. Don’t start eight years behind. CentOS 7 will be EOL in less than two years.
If you like CentOS, choose Rocky 8 or Alma 8 or RHEL 8 (9 is supported, but much less well-tested at the moment).
I was able to connect to the centos repositories… The network is fine unless there is a conflict with the fqdn http://imatrdev2.hostnode.ca/
I was using Cetnos 8 but as if yesterday Virtualmin is pooched - starts dropping connection after I deleted a virtual server only one of six virtual servers - Lets Encrypt tab gone. File Manager gone. Cannot update virtual server, apache stopped working - have to abandon and start over with a new OS… so thought I would go back to Centos 7 as it was always stable for me. BTW I didn’t fiddle at all with anything - just removed a virtual server through the Delete Virtual Server interface.

sorry about the other rant - long night
You need to update (yum update). That means you have an very old ca-certificates package.
But, again, you really should reconsider installing on CentOS 7. It is 8 years old, and will reach end of life in less than two years. Every package in CentOS 7 is ancient.
