Hi, I created a parent object with field "dns name" = complete url, that should be checked. Under the parent object I created a sensor "ssl certificate". I would like to check, if the fingerprint of the certificate is the right one. But I get the error message "Failed to establish secure connection [Step 0] Socket Error # 11001 Host not found. [Step 1] Socket Error # 11001 Host not found. [Step 2]..." But the url in a browser opened on the prtg node works fine. What is the real error behind this misleading error message? Regards Michael
