Basic HTTPS monitor

GET / is an HTTP 0.9 request which the web app might not support. The error indicates HTTP version is not found, so this does seem likely. Can you try testing using this send string:

 

 

GET / HTTP/1.0\r\nHost: \r\nConnection: close

 

 

For v9.4+ you don't need to append any extra \r\n's to the send string. For previous versions, you can check SOL2167:

 

 

SOL2167: Constructing HTTP requests for use with the HTTP or HTTPS application health monitor

Once that is working, it would be good to configure a receive string to ensure the server responds with specific content. You could try '200 OK' to start with.
