"Invalid API request" when using CURL_EXEC - php

Question

i have the following php code that calls an API:
$forcetest = 1;
$url = "https://www.website.com/api/pointTotal.php?userId=" . $userId;
if ($forcetest || (isset($_SERVER['ON_TEST_SERVER']) && ($_SERVER['ON_TEST_SERVER']))){
$url = "https://wwwtest.website.com/api/pointTotal.php?userId=" . $userId;
}
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_RETURNTRANSFER => 1,
CURLOPT_URL => $url
));
curl_setopt($curl, CURLOPT_HTTPHEADER, array(
'sharedSecret: abc123',
));
//curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true); //tested to see if this would work, didn't seem to matter
// Only do this if on dev/test
if ($forcetest || (isset($_SERVER['ON_TEST_SERVER']) && ($_SERVER['ON_TEST_SERVER']))) {
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
}
$response = curl_exec($curl);
print($response);
if(!$response){
die('Error: "' . curl_error($curl) . '" - Code: ' . curl_errno($curl));
}
my problem is when going to production (i.e. $forcetest = 0;) it works just fine, calling the prod api and using the prod database. if i switch it, and it goes to the wwwtest subdomain to call the test api, i get the error returned
{"success":false,"errors":["Invalid API request"]}
"invalid api request" isn't something in the api's code, so it seems to me that its something curl_exec is doing/erroring on but i can't figure out what. if i go to the api's directly, they both return the correct information in my browser, so i know it's up and working. is it maybe a cert issue or some sort of xss setting on that subdomain/server that's causing it to error? i'm kind of at a loss.
Thanks in advance.
edit: CLI curl command and header output:

also added this to the php code making the call
curl_getinfo($curl, CURLINFO_HEADER_OUT) and it prints out a 404 which is what seems to be the problem but going to the url it's curl'ing immediatley returns the correct result so i'm not sure what's causing the 404

Sorry, just now saw this question was still open. The problem turned out to be bad internal DNS. the code and the curl we're all correct, i had to rely on the sys admin's to resolve it.
