Is there a conflict between Debian Bullseye and nginx?

I am running Debian Bullseye: this is a stripped down Command Line only install without a GUI. It runs apache2 and ISC-BIND only in a VirtualBox VM.

# uname -r
5.10.0-19-amd64
# nginx -v
nginx version: nginx/1.23.2
# apache2 -v
Server version: Apache/2.4.54 (Debian)
Server built:   2022-06-08T16:00:36

This is NOT commented out:
pid /run/nginx.pid; 

apache2 - runs with no problems. syslog is clear of any error message from anything. 

I was looking to use LetsEncrypt which uses nginx.

** While apache2 is running, if I try to start nginx I get this. **

If I stop apache2 then nginx loads **BUT** then apache2 refused to load with this statement:

Starting apache2 (via systemctl): apache2.serviceJob for apache2.service failed because the control process exited with error code.
See "systemctl status apache2.service" and "journalctl -xe" for details.
