HTTPS Monitor not working as expected

I have created an HTTPS monitor as follows:

       GET /idauth/isAlive.jsp\r\n

The receive string is set as:

    ALIVE

There are 2 servers and when i curl them i get the following:

First Server

    curl -k https://server1.domain.com:8443/idauth/isAlive.jsp


    

    
        OpenAM
    

    



    Server is DOWN


    

    

Second server:

    curl -k https://server2.domain.com:8443/idauth/isAlive.jsp

    

    
      OpenAM
    

    



    Server is ALIVE: 


    

    

However. Both servers are being flagged as unavailable.

If I change the receive string to DOWN - both servers are flagged as available.

I have changed curl to verbose to check for separate words showing ALIVE/DOWN but this doesnt show anything:

     curl -k -v https://server2.domain.com:8443/idauth/isAlive.jsp
