2.2 Credit Card Checkout "An error occurred on the server. Please try again"

SOLVED

2.2 Credit Card Checkout "An error occurred on the server. Please try again"

Using Magento 2.2.1

Order does not go to success page, but shows in Admin.  Payment shows in Authorize.net which means customer's credit card is charged but customer gets no email of order confirmation.

Hi @shebafoods,

 

Can you check (and/or activate) the Magento logs to try to find more details about the error? (if the problem is on the store side).

Hi Damian,

Thanks for your prompt response. I *REALLY *appreciate it.

Found the issue in the exception.log:

The transaction was declined because the response hash validation failed.

Entered the MD5 Hash in Authorize.net into Sales > Payment Methods >
Authorize.net > Merchant MD5 and problem solved :=)
