I am using an http sensor to monitor my web application ... but for some time, I have observed dead connection times while I normally access my application .. what could be the cause?

here is the overview of my http sensor:

Failed to establish secure connection [Step 0] Socket Error # 10060 Connection timed out. [Step 1] Socket Error # 10060 Connection timed out. [Step 2] Socket Error # 10060 Connection timed out. [Step 3] Socket Error # 10060 Connection timed out. [Step 4] Socket Error # 10060 Connection timed out. [Step 5] Socket Error # 10060 Connection timed out. [Unsecure] IOHandler value is not valid

here are the parameters of my http sensor:

Hello mohamadou,

The error message 10060 is a connection time-out error that usually appears when the client does not receive a response from the server for a specific command. Please remember that the URL will be accessed by the PRTG Probe on which you've deployed the sensor, make sure that the said probe has access to the URL.


Kind regards

Support, Thank you for your reply.

I realize that every 15 minutes the probe did not access the url ... on the other hand at the same time the url is normally accessible elsewhere in my network ... Is there a configuration error in PRTG on my side? because my url is normally accessible elsewhere and at any time but in the PRTG server the url is inaccessible every 15 minutes ...

Is there a configuration error in PRTG on my side?

Hello mohamadou,

it could be possible that there is a configuration error on your host machine of your PRTG device. In addition I would check if there is any event log.


Kind regards
