This single-instance application could not connect to the original instance.

Posted on by 10

Hello Team,

We have a Microsoft Dynamics AX2012 R3 CU13 environment with an AOS, one Management Reporter, and a Database server.

For last few months, our customers when generating reports via the management reporter designer were frequently (twice or thrice a week) facing the issue with the screenshot below,

This-single_2D00_instance-application-could-not-connect-to-the-original-instance_2E00_.png

We upgraded the kernel on AOS server a couple of weeks ago and had faced the issue for the very first time after the update.

Note: We are using the latest version/update of the management reporter server

Could any one please let me know,

As why this issue is occurring?
What more can be done to get rid this issue for good?

    Hi Andre,

    Thank you for your response.

    The issue started a few months ago and the frequency of the error being received was twice or thrice a week at that time.

    As a fix, we upgraded the kernel on the AOS server and it is now working very well as we had received this error just once after the kernel upgrade.

    It would be very helpful if the reason or any information close to the source or related to this issue can be shared.

    Note:

    • Going back to the previous version will not be feasible
    • Unfortunately, not much shared by Microsoft Support except for a few basics troubleshooting/information collection steps
    • We are launching Management Reporter from within the AX app as shown in the image below whereas no issues when launching from the Management Reporter server

    Please let me know if you have any questions or need further information.

    Hi Asad89,

    When exactly did this issue start? You are mentioning two different time frames. First you tell about "for last few months" and then "we upgraded the kernel on AOS server a couple of weeks ago". Did it start after upgrading the kernel or already before?

    I would suggest to contact Microsoft Support with this issue. You can also try to go back to the previous kernel version.
