After successfully receiving an access token from the `oauth2/authorize` endpoint, I have attempted to submit the access token to `sharing/get_shared_link_metadata` along with the URL of a shared link. Several attempts have returned me with a 401 error. So I tried submitting an access token, which was generated from the app page, but with no success. However, when I copied/pasted my code to phpfiddle.com, the request returned successfully. So the issue seems to exist only in the request from my virtual server.

I have no clue what issue could exist in a request from a virtual server, so any help would be greatly appreciated.

request:

public function getDropboxMetadata($url, $token)\n{\n\t$ch = curl_init();\n\n\tcurl_setopt($ch, CURLOPT_URL, 'https://api.dropboxapi.com/2/sharing/get_shared_link_metadata');\n\tcurl_setopt($ch, CURLOPT_HTTPHEADER, [\n\t\t'Authorization: Bearer ' . $token,\n\t\t'Content-Type: application/json']);\n\tcurl_setopt($ch, CURLOPT_POST, true);\n\tcurl_setopt($ch, CURLOPT_RETURNTRANSFER, true);\n\tcurl_setopt($ch, CURLOPT_POSTFIELDS, json_encode(['url' => $url]));\n\n\t$result = curl_exec($ch);\n\n\tcurl_close($ch);\n\n\treturn $result;\n}

response:

error: {\n\tcode: 401,\n\terrors: {\n\t\t0: {\n\t\t\tdomain: \"global\",\n\t\t\tlocation: \"Authorization\",\n\t\t\tlocationType: \"header\",\n\t\t\tmessage: \"Invalid Credentials\",\n\t\t\treason: \"authError\"\n\t\t}\n\t},\n\tmessage: \"Invalid Credentials\"\n}

My issue is not with the code itself, because I've received a successful response when I've used it on phpfiddle.com. My issue is that I'm getting an error response on my local virtual server, and I have no clue why. I am hoping you may have some insight.
