Web Application Firewall - Real webserver "in error"

I' am trying to setup an Web Application Firewall on my Sophos UTM 9. I've configured some real webservers and one virtual webserver. In the virtual webserver on the left always appears an icon that says "in error". I get nothing in the logs. What could cause this problem?

  • I ran into this after a power failure at my house.  For some reason, it would not bind port 80 to my IPv6 address:

    # /var/mdw/scripts/reverseproxy restart
    :: Restarting reverseproxy
    reverseproxy not running
    :: Starting reverseproxy

    I was able to work around this by disabling IPv6 temporarily, then restarting the reverseproxy service again.

    Has anyone else seen this?
