I am running v1.39h on a dedicated server and have been getting intermittent error with Authorize.net AIM. This install has been running for about 1 year. I have called my host and eprocessing network and they do not have any ideas on why this happens. I have searched and most people with similar issues have been constant. I found one post on here that had the same issue from 2010, but no replies in the thread and that thread is closed.
The errors from this weekend on two orders was
Comm results: 28 SSL connection timeout
This error did not charge the card.
The errors from two orders today are;
Comm results: 28 Operation timed out after 15000 milliseconds with 0 bytes received
With this error, the credit card was charge, but our site has no record of the order. When this happens, the customer sees a red error box pops up that says "Communications error, Please notify webmaster- Your credit card could not be authorized for this reason. please correct the information and try again or contact us for further assistance"
Any ideas as where to look or any settings that may be causing this would greatly be appreciated.
