Apologies if I missed a step updating the topic, but thanks for the response and this did the trick. For the benefit of anyone who may run across this in the future, the *wordpress.conf* file referenced is the Apache config file (on Debian-like systems, located at /var/www/apache2/sites-available). At least if using Letsencrypt, the SSL config needs to be updated as well.
Thanks again for the help.
