HTTPS monitor not working

My HTTPS monitoring is not working. The page response is fine using "curl -k". Is there any way I can ignore the cert warning for HTTPS monitor? Does it really matters? How do I troubleshoot monitor? I tried with bigd.debug however couldn't find anything.

    Do the Pool Members that you have applied the HTTPS Monitor have an SSL Certificate applied to them?

    If curl -k https://1.1.1.1 is working, you should be able to get the monitor to work as well. LTM doesn't check the server cert validity by default with an HTTPS monitor.

     

     

    Which LTM version are you running? What do you have configured for the HTTPS monitor send and receive strings? What does the server log show as a response code for the monitor requests?

    Do your web servers support HTTP 1.0? Unless you specify 1.1 in the get request the F5 monitor defaults to 1.0. Have you tried specifiying an HTTP1.1 GET request in the monitor? 

    send "GET /index.html HTTP/1.1\r\nHost: mysite.com\r\nConnection: Close\r\n\r\n"
