ajp or http(s) proxy, error happens with both
Visiting jenkins running on https://www.artop.org/builds/manage, always shows the warning "It appears that your reverse proxy set up is broken." In the configured logger "hudson.diagnosis.ReverseProxySetupMonitor", i get for every single visit two requests shown like bellow. The second one has always the context-path "builds" twice.

When monitoring the logs, while navigating around on the Jenkins instance, i can only get a hit for "builds/builds" or "jenkins/builds", when clicking on https://www.artop.org/builds/manage.
