Authentication error need_login when using REST v10

Sugar - v9.0 Enterprise running on localhost using PHP v7.1.35

Wordpress custom plugin running on localhost using  PHP v7.1.35

Ive got a strange problem with my local instance of sugar. I have a local copy of my live cloud install to facilitate development, however this morning I'm getting the following error when running any api call to my local sugar

{"error":"need_login","error_message":"No valid authentication for user."}

If i run the same API call in postman I get the proper return but my local wordpress app I get the error

PHP Error Log

[15-Jul-2019 10:12:41 UTC] Token: 24e46b36-541e-4246-9df7-56c904fd375c

[15-Jul-2019 10:12:41 UTC] Response: {"error":"need_login","error_message":"No valid authentication for user."}

My Curl call to the API endpoint "http://sugarcrm.localdev/rest/v11/Contact/SupportLogin"

static function getSugar($get,$url,$force = false) {

self::connect_sugarcrm();

$curl = curl_init($url);
curl_setopt($curl, CURLOPT_HEADER, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, 'GET' );
curl_setopt($curl, CURLOPT_POSTFIELDS, $get );
curl_setopt($curl, CURLOPT_HTTPHEADER, array(
'Authorization: Bearer '.self::$tokens->access_token,
'Content-Type: application/json',
)
);

$json_response = curl_exec($curl);
$status = curl_getinfo($curl, CURLINFO_HTTP_CODE);

if (self::$log) {
_log('Token: '.self::$tokens->access_token);
_log('URL: '.$url);
_log('Data: '.$get);
_log('Response: '.$json_response);
};
curl_close($curl);
$result = json_decode($json_response);
return $result;
}

If i change my target url to my live sugar instance then everything works fine so this is a local issue just wandering if anyone else has come across this and found a fix. Ive also tried looking through the sugar log and there is nothing there that indicates a problem

if i run the API call in postman i get
