Hi John,

I found the same issue.

In my case the problem was the Content-Lenght and I resolved it in this way:

I have created a JSON string and I have counted the length of it

 

set json_data "\{ \"ipAddress\" : \"$client_ip\", \"userAgent\" : \"$user_browser\" \}"
set cnt_length [string length $json_data]

 

After that I have populated the POST request

 

set data "POST /test HTTP/1.1\r\nHost: www.test-acme.local\r\nAuthorization: Basic cGlwcG86cGx1dG8=\r\nContent-type: application/json\r\nContent-Length: $cnt_length\r\n\r\n$json_data"
set send_info [send -timeout 3000 -status send_status $conn $data]

 

I hope this help you.

Sorry for my terrible english
