          Description Original: 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.
