To know the exact reason why it is happen, please open below file:

vendor/magento/module-checkout/Model/PaymentInformationManagement.php

then comment out the try, catch and put code to place order directly as below:

Replace below function

public function savePaymentInformationAndPlaceOrder(
    $cartId,
    \Magento\Quote\Api\Data\PaymentInterface $paymentMethod,
    \Magento\Quote\Api\Data\AddressInterface $billingAddress = null
) {
    $this->savePaymentInformation($cartId, $paymentMethod, $billingAddress);
    try {
        $orderId = $this->cartManagement->placeOrder($cartId);
    } catch (\Exception $e) {
        //var_dump($e);
        throw new CouldNotSaveException(
            __('An error occurred on the server. Please try to place the order again.'),
            $e
        );
    }
    return $orderId;
}

To

public function savePaymentInformationAndPlaceOrder(
    $cartId,
    \Magento\Quote\Api\Data\PaymentInterface $paymentMethod,
    \Magento\Quote\Api\Data\AddressInterface $billingAddress = null
) {
    $this->savePaymentInformation($cartId, $paymentMethod, $billingAddress);
    //try {
        $orderId = $this->cartManagement->placeOrder($cartId);
    /*} catch (\Exception $e) {
        //var_dump($e);
        throw new CouldNotSaveException(
            __('An error occurred on the server. Please try to place the order again.'),
            $e
        );
    }*/
    return $orderId;
}

Now, try to place order again. You will be able to see the details error in log file or may be in console.
