Hello Steve.
Connection error with MQ Queue Manager occurred in a production system. We have a queue manager running on IBM MQ Appliance, so this is the first time I have encountered an error related to the disconnection of an existing connection to the queue manager. While maintaining other information systems that work through the MQ client, the loss of connection to the MQ queue manager caused by an error in the application software causes error messages on the MQ side of another type.
Since it is now difficult to find documentation that describes the specifics of DataPower's interaction with the MQ manager, as well as any additional information on this topic, I would like to receive links to documentation or presentations on this topic.
So the error is not of a periodic nature, we have not opened a case in IBM Support so have not yet been able to understand the nature of the occurrence of such an error.

Hi Andrii,
Given this is a production environment, have you opened a PMR/support ticket?
Best Regards,

Good afternoon colleagues.
In recent days, problems have begun to arise in the interaction of our productive DataPower with the queue manager deployed on the IBM MQ Appliance. Errors of the following type began to appear on the DataPower side:
[0x808000f2][XXX4][error] mpgw(XXX4): trans(1018701471)[error][ip_client_1] gtid(e6b99f89655f4d233cb8269f): XSLT custom log message ' sender: TESTXXX400 signer: TESTXXX400 action:Receive msg:Код помилки: 1010 Пояснення: Failed to establish a backside connection'
[0x01130006][mpgw][error] mpgw(XXX4): trans(1018701471)[error][ip_client_1] gtid(e6b99f89655f4d233cb8269f): Failed to establish a backside connection
[0x80e0012b][mpgw][error] mpgw(XXX4): trans(1018701471)[ ip_client_1] gtid(e6b99f89655f4d233cb8269f): Backside header ('N/A') failed to parse due to: Failed to establish a backside connection, URL: dpmq://<Queue Manager>?ReplyQueue=TEST;GMO=2;TimeOut=2;ParseProperties=on
On the IBM MQ Appliance side, errors are generated stating that the initiator of the connection termination was IBM DataPower.
We could not find in the IBM DataPower documentation an error message with code 1010 that occurs when connecting to an SSL queue manager on an IBM MQ Appliance. It is also not clear why DataPower broke the existing connection with the queue manager on the IBM MQ Appliance.
