However, I still get the above error when trying to access the server's

httpd (Apache) web server error_log:

daemon after multiple tries
Googling "unable to connect to cgi daemon" turns up a lot of references
to the httpd 'mpm' module. Hoping that folks who are familiar with
Apache module innards might have some advice here.
How old of a system did the original install come from? The reason I
mention is the thing I completely forgot about when upgrading my
BackupPC from Centos 8 Stream to Fedora Server 39 is the apache
configuration:
Just figured this out a little while ago. It is Apache's module config.
In /etc/httpd/conf.modules.d, uncomment the line:
LoadModule mpm_prefork_module modules/mod_mpm_prefork.so
Comment out the line:
#LoadModule mpm_event_module modules/mod_mpm_event.so
Restart httpd and we're good, though httpd complains:
[Wed Feb 21 14:35:45.935781 2024] [http2:warn] [pid 22031:tid 22031]
AH10034: The mpm module (prefork.c) is not supported by mod_http2. The
mpm determines how things are processed in your server. HTTP/2 has more
demands in this regard and the currently selected mpm will just not do.
This is an advisory warning. Your server will continue to work, but the
HTTP/2 protocol will be inactive.
Since the only purpose of this Apache server is BackupPC, I think I can
ignore this.
Thanks to all.
