HTTP GET Probe Monitoring

I am trying to monitor our web servers from our load balancer with an HTT probe  This probe keeps failing.  Its monitoring a Windows sharepoint server, and I can get to the test page with my credentials, but the Probe seemingly cant pull it.  Is there something in here I am doing wrong?  I have attached a screen shot of the probe for reference. I keep getting probe failed.  Ive tried a lot of different permutations of this probe config with no success.   Any help with anyone who has done this before would be awesome

Hi,What does last disconnect


What does last disconnect err says? Please do show probe <probe name> detail. Also, it would be best to take pcap on the switch where ACE and server are connected to see what exactly is going on.

Hi,So what is the expected


So what is the expected response code you have configured on ACE? If you have not configured any then ACE assumes it by default to 200OK if i am not wrong and i see above you are getting status code as 401 and last disconnect err: Received invalid status code.

Take a packet capture on client (when you access server directly) and look at HTTP header. Ensure that GET sent in there and configured on ACE is correct. Also, put in the response code if it is other than 200. That should take care of the issue.
