POST API Request not Identical to running locally

[admin]

One more thing to try is to send a request using raw sockets. Modify host, uri and body as needed.

Code:

host = '192.168.0.9'
uri = '/public/test.lp'
body = 'a=b&c=d'

sock = require('socket').tcp()
sock:settimeout(5)

res, err = sock:connect(host, 80)

if res then
  crlf = '\r\n'
  sock:send(
    'POST ' .. uri .. ' HTTP/1.1' .. crlf ..
    'host: ' .. host .. crlf ..
    'connection: close' .. crlf ..
    'content-length: ' .. #body .. crlf .. crlf ..
    body
  )

  res, err = sock:receive('*a')
  sock:close()

  log(res, err)
else
  log('connect error', err)
end

If it still does not work then check the whole raw request in Postman (starting from POST .. HTTP/1.1).
