Sometimes something wrong is going on withing a payment process - certain orders are not being received by admin.
This is happening very rare - in some cases there is no record of the order.
After some investigation, we saw that in such cases immediately (2 minutes) after the payment successfully received from the gateway, the "The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel" error raised by the "Keep alive" schedule task shows. Can it be the cause of the problem and how? Does it means the session is getting lost?
Any help will be greatly appreciated.
