HTTPS Monitor Health - Receive String 200 OK Not Working

Hello,

Though we receive in https response header "HTTP/1.1 200 OK", the same string used as receive in Health Monitor does not work. F5 seems to ignore any character after HTTP/1.1.

In sum:

Not Working:
                    HTTP/1.1 200 OK
                    HTTP/1.1\s200
                    HTTP/1\.(0|1)
                    HTTP/1\.(0|1) (200)
                    HTTP/1\.(0|1)\s200
                    HTTP/1.1 200 OK
                    HTTP/1.1\s200\sOK
                    200

 

                    Only Working:
                    ==> HTTP/1.1 
                    ==> OK||200
                    ==> <bank>

Type: https, Alias Service port 443.

VIP is using TCP profile.
