HTTPS Health monitor with post is failing...

Hello Guys,

I trying to do an https monitor with post, with curl from TMSH is working since with standard https monitor is failing

I followed other discussion about that unsuccessfull.

This is the working curl:

[keli078@cdm-sf-lb01:Active:Changes Pending] ~ # rdexec 50 curl -k 'https://sflnx006058.utenze.bankit.it:8088/services/collector/raw' --header 'Authorization: Splunk ab4cdbb0-e322-4a75-a182-668e9f7f30ed' --header 'Content-Type: application/json' --data 'lb-probe'

{"text":"Success","code":0}

[keli078@cdm-sf-lb01:Active:Changes Pending] ~ #

This is my https monitor:

send "POST /services/collector/raw HTTP/1.1\r\nAuthorization: Splunk ab4cdbb0-e322-4a75-a182-668e9f7f30ed\r\nContent-Type: application/json\r\n\r\n <LB_PROBE>"

recv Success

What I wrong?

Many thanks for support.

Fabrizio
