Hi,

When I am trying to monitor a server using normal HTTP sensor it is giving the below error. HTTP/1.1 403 Forbidden I tried in re creating the sensor, giving the URL but still gets an error. We are using PRTG V 7.1.1

Thanks, Kuldeep

Hi,
this return value indicates that PRTG is not allowed to access the page you set up.
Please try if you can access the page via browser. Does that work?
Best regards

I'm experiencing the same problem. Having "HTTP/1.1 403 Forbidden" when monitoring a website with the http or http (advanced) sensor. If i open the website with a normal browser from the probe-pc, everything works fine.

any solution for this?

Hi,

this behaviour may happen if you are using settings to keep out for example robots or older browsers. Depending on which kind of http-sensor you are using you may modify the user-agent to a not filtered user-agent or you need to allow the default 'Mozilla/5.0 (compatible; PRTG Network Monitor (www.paessler.com); Windows)' which is sent by PRTG.

Kind regards
