Problem:
When trying various ways to register a content host to Katello, it fails with message “HTTP error (400 - Bad Request): Problem creating unit class ConsumerDTO”.
Expected outcome:
When using subscription-manager command with an activation key it would register as normal.

Other relevant data:
In addition to the registration issue, Apache won’t start after latest general updates.
Apache error message " httpd: Configuration error: More than one MPM loaded"
I worked around it by commenting all LoadModule lines in /etc/httpd/conf.modules.d/00-mpm.conf. Once I did that it still would not start because multiple configuration files were trying to use port 443. This port is defined in both /etc/httpd/conf.d/05-foreman-ssl.conf and /etc/httpd/conf.d/ssl.conf. To work around the port issue, I simply removed /etc/httpd/conf.d/ssl.conf. Once those items were complete all services started without issue.
Still my last item that isn’t working is registering content hosts.
Output from log /var/log/foreman/production.log during a registration attempt.
