curl Failed to connect to domain.com port 9081: Connection refused

[niman]

In my localhost it work correctly but when it uploaded on my shared hosting it shows curl errors "Failed to connect to domain.com port 9081: Connection refused" .
Others curl request works fine on my shared host.
Anyone can give a solution?
My curl request is below

$bkash_url = "https://www.domain.com:9081/dreamwave/merchant/trxcheck/sendmsg?user=<USENAME>&pass=<PASSWORD>&msisdn=<MERCHANT_NUMBER>&trxid=<TRANSACTION_ID>"";
$curl = curl_init();
    curl_setopt_array($curl, array(
        CURLOPT_PORT => 9081,
        CURLOPT_URL => $bkash_url,
        CURLOPT_RETURNTRANSFER => true,
        CURLOPT_ENCODING => "",
        CURLOPT_MAXREDIRS => 10,
        CURLOPT_TIMEOUT => 30,
        CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
        CURLOPT_CUSTOMREQUEST => "GET",
        CURLOPT_HTTPHEADER => array(
            "cache-control: no-cache",
            "content-type: application/json"
        ),
    ));
    $response = curl_exec($curl);
    $err = curl_error($curl);
    $http_code = curl_getinfo($curl, CURLINFO_HTTP_CODE);
    curl_close($curl);

I removed the domain name from your post but before then I attempted to connect using curl over port 80 but I'm unable to even make a curl request to that server, I'd suggest discussing this issue with your hosting provider.

curl -vv domain.com
