Answer 1

Please check the function isAvailable() of the class Sslwireless\Sslcommerz\Model\Sslcommerz.php

As per the code, your payment method will not available if there is no shipping method. For virtual product or downloadable product only quote, no shipping carrier is available in magento.

I have updated the isAvailable function of the class Sslwireless\Sslcommerz\Model\Sslcommerz.php to check if quote contains only Virtual products and has not any Shipping Address then the isAvailable function will returns true and your Payment method will be shown on checkout page.

public function isAvailable(\Magento\Quote\Api\Data\CartInterface $quote = null)
{
    if ($quote === null) {
        return false;
    }
    if(!$quote->getIsVirtual() && isset($quote->getShippingAddress()->getShippingMethod())){
     return parent::isAvailable($quote) && $this->isCarrierAllowed(
        $quote->getShippingAddress()->getShippingMethod()
     );
    }else{
        return true;
    }
}

Answer 2

At last i Got my solution (May be Someone will be help)

return strpos($this->getConfigData('allowed_carrier'), $shippingMethod) !== false;

Change as return strpos($this->getConfigData('allowed_carrier'), $shippingMethod) !== true;
