Since early March, 2018 the calls to our "relay response" from Authorize.net are triggering E-mails that look like this on about 5% - 20% of our transactions:

    Your script timed out while we were trying to post transaction results to it.

    Transaction ID: 40600965353

    Transaction Result: This transaction has been approved.

We did nothing to our server: no updates, nothing. Also, our Apache logs clearly show that there is no attempt by Authorize.net to even contact our URL with the relay response. There is simply nothing. We are using TLS 1.2

We are not alone. Others on the community forum appear to be experiencing these same errors.

For example: https://community.developer.authorize.net/t5/Integration-and-Testing/No-Relay-Response-from-Authoriz...

We wrote to developer support requesting help last Sunday (March 25th, 2018) but got no response whatsoever.

This is starting to look like an issue with one of Authorize.net's servers. What can we do to encourage Authorize.net to take this issue seriously and check their servers and configuration setups?
