  • Few tips:

    • Perform telnet to the pool member first.


    • If the above passes, then make curl test to see whats the data you get,

    curl -kv

    When you run the above, you should see the string

    , if you dont see that it means, the backend server is not returning it.

    • If you think that server does returns the string
      but still LTM is not finding it, there is a limititation to it too only if the string is placed after 5,120 bytes into HTTP data. Refer the below article, if this applies in your case.

    Is your ltm pool marking your server as up or down for now ?

    • If your ltm pool is marked down, try changing the recv string to
      200 OK
