Last week one of our switches all of a sudden got an alert on its HTTP sensor stating:
Error connecting with SSL. EOF was observed that violates the protocol
After restarting the switch, sensor went back to status OK. 4 days later, the problem reoccured.
Sensor has been running fine since we've implemented PRTG about 3 months ago. No changes were made to the switch's configuration or work load. (The switch doesn't even have any devices attached to it, as it is our backup switch)
HTTP sensor settings are:
- Timeout (Sec.): 60
- URL: https:///
- Request Method: GET
- SSL Method: SSL V2 or V3
What is causing this error? How do we resolve it.
Many thanks and congratulations to the entire PRTG team. You guys made an awesome piece of software!
