I am using Magento ver. 2.1.2. Some of our customer complain that they can't checkout with Credit Card (Authorize.net). A sorry message "sorry but something went wrong" showing when checkout. We have checked the issue also found the problem using credit card (testing mode).
But when I check in admin, order was placed as Pending status.
I have contacted with the theme (Porto) support section, but they replied that "payment method integration is core functionality of Magento default, not theme related". So, they are are unable to help about this issue.
Can you please help me resolve the issue.
Regards,

This error generally comes when server connection timeout of api has been expired. For authorize.net it is 45 second. you can check it from here:
Magento\Authorizenet\Model\TransactionServiceCONNECTION_TIMEOUTthere are two option for solve this problem you can check by increase your timeout or check with your authorize.net team.
