HTTPS Sensor Error



I am trying to monitor a SSL enabled site using a standard HTTP sensor, but pointing it at a SSL URL.

We have many of theses sites being successfully monitored, but this particular one fails. The error given in PRTG is:

HTTP/1.1 410 Gone

We can browse to the site with no problems, we know the SSL certificate part of the site is working as we have set a SSL Certificate sensor against it as part of the troubleshooting, but nothing we have done so far has cleared the error.

Both the device and the sensor are using the correct DNS name for the site.

We have been able to replicate this error in a browser, but only by having the browser point to the IP of the site.

The sensor log in PRTG are very sparse of useful information, is there any way of getting the transaction details when PRTG polls the sensor?

Any help would be most appreciated!

The 410 is returned by the webserver, telling you that an old resource is permanently unavailable and has no forwarding address. The effect is basically the same as with the more common 404 (Not Found) error.

To see what page is exactly requested by the sensor you could use Microsoft Network Monitor to capture requests send to the webserver.
