I have been using py39-certbot-2.6.0,1 for sometime now without any issues.  However, earlier this month it started generating errors:

Renewing an existing certificate for sermon-archive.info and 5 more domains
Failed to renew certificate sermon-archive.info with error: Could not bind TCP port 80 because it is already in use by another process on this system (such as a web server). Please stop the program in question and then try again.

Huh?  Of course there is a web server there.  That's why I need a certificate.  Anyone know how to fix this issue, or should I switch to some other LetsEncrypt client?  Thanks,
