I ran this command:

It produced this output:

My web server is (include version):

The operating system my web server runs on is (include version):

Were you able to find out if a newer version of urllib3 was available on your OS, or to try certbot-auto?

If the Certbot installation is managed by Virtualmin somehow, you may need to ask their support about it.
