Monitoring a website using PRTG, infrastructure changes means it is now reached via a loadbalancer that automatically rewrites the http request so http://www.domainname.com becomes https://domainname.com Works fine from a browser but the PRTG monitor doesn't seem able to follow the rewrite and shows the site as down. Suggestions please on what to change to fix it, I'm using HTTP advanced.

Hello David,
This sensor won't follow the redirection, but you can setup a powershell sensor that checks for the response code which will tell you if the redirection works.
In order to do this follow this KB-Post:
The right response code, if it is redirected properly, is "302"
For any further questions or issues, we're glad to help.
Kind regards,
Birk Guttmann, Tech Support Team
