What happens if you try:

$curl = curl_init();
curl_setopt_array($curl, array( 
   CURLOPT_RETURNTRANSFER => 1,
   CURLOPT_HEADER => 1,
   CURLOPT_VERBOSE => 1,          
   CURLOPT_URL => 'http://192.168.100.4:9710/http/send-message?message='.$message
));

if(curl_exec($curl) === false) {
    echo 'Curl error: ' . curl_error($ch);
} else {
    echo 'Success!';
}

One thing I noticed was that you were trying to access the port twice.
