Some of our SSL Certificate Sensors show the error: Failed to establish secure connection [Step 0] Socket Error # 10061 Connection refused. [Step 1] Socket Error # 10061 Connection refused. [Step 2] Socket Error # 10061 Connection refused. [Step 3] Socket Error # 10061 Connection refused. [Step 4] Socket Error # 10061 Connection refused. [Step 5] Socket Error # 10061 Connection refused.
The long error message with different steps shows that the sensor cycles through different SSL protocols, each one resulting in an error. Possible error causes include a wrongly entered device address (must be IP or DNS name, without the "https://" part.) Also, network connectivity issues are a possible cause.
Please check the corresponding certificate with the browser on the PRTG server. Is it displayed correctly there?
