no test connection to breitbandmessung.de if HTTP(S) Proxy active
We don't get any results from breitbandmessung. de if proxies for http/https are active, even if gateway av, webblocker and APT blocker are not activated.
Which settings could be the cause of this issue.

Hello @WolfgangH
-Do you see any errors in your traffic monitor?
-Are you able to access https://www.breitbandmessung.de/ via a packet filter?
-That site appears to resolve to only 88.217.175.198 -- do you see any return traffic if you use a tool like TCPDUMP on the firewall? If you're not seeing a response, the issue may be upstream from your firewall.
See for TCPDUMP:

You can use an advanced argument like
"-i eth0 host 88.217.175.198 and (port 80 or port 443 or icmp)" to filter for that traffic.
