Working on authorize.net sandbox integration in Magento 2.2. I have followed instructions in setting up authorize net credentials. But when i try to place an order i receive an error as below
"An error occured on the server. Please try to place the order again"
But when i check the authorize.net sandbox account panel, there is an successful payment transaction. Also when checking in Sales->Orders there is a new order with no payment received.
Also using this link i tested the response of transaction.dll it says failed to load response.
My assumption is payment is authorized but it seems no response is received from authorize net.
Any assistance would be really appreciated .
Thanks in advance
