I have installed PRTG yesterday and it works fine. There is just one problem with the HTTP Sensor. It Shows the red exclamation mark and says 'HTTP/1.1 407 Proxy Authorization Required'. The Proxy Settings are configured correct. We are useing an Sophos UTM Firewall maybe this is the Problem.

Hello,

Thank you for the KB Post. Please do upload and share some screenshots showing the settings of the sensor as well as the configured Proxy Settings. Thank you!

Also, which exact PRTG version are you running?

best regards.
