Hello,
After upgrading PRTG to version 22.2.77.2204, one of our HTTP sensors is no longer working and throws an error message of:
HTTP/1.1 406 Not Acceptable
The sensor had been working prior to updating PRTG to version 22.2.77.2204. The endpoint that we're monitoring is a Kubernetes RESTful API that just returns a JSON-formatted page with component status. It uses a self-signed certificate and we can browse to the endpoint with Google Chrome and MS Edge without any issues and get a 200 response in those respective browsers.
Can you please offer any insight into how to resolve this issue?
Thanks.
