Upgrading Matomo PHP

This afternoon I’m adding https://digital.grinnell.edu (site ID is 17) to my own Matomo instance and I’m prompted to upgrade PHP on that Matomo droplet (DigitalOcean). I did so quite easily following Upgrade PHP from 7.2 to 7.4 on CentOS 8 and Apache. I’ve also updated my Drupal version, and some modules, in https://digital.grinnell.edu along with adding the matomo module, but that module is now reporting:

    The validation of "http://analytics.summittservices.com/matomo.php" failed with error "Error opening socket ssl://analytics.summittservices.com:443" (HTTP code 0).
    The validation of "https://analytics.summittservices.com/matomo.php" failed with error "Error opening socket ssl://analytics.summittservices.com:443" (HTTP code 0).

Hmmm…wonder what’s up with that?

So, I tried this…
