Importing updates on Azure IoT Hub

I am trying to import an update on my IoT hub to deploy on a device. I am constantly getting error saying that:: error importing update due to exceeded limit(attached screenshot). Now I have uploaded updates with same provider and name few weeks back and I know it works. Suddenly I am getting errors. I know the update is with a new version number so there are no updates before. Everything seems fine with the update file and manifest.

Also, few days back I was having issues in uploading update and was getting error saying the manifest format has issues. This works now magically with same updates and manifest. So maybe Microsoft is doing something here.

My question is now how do I make it work? Can someone support me with this?

    Hi Vineet ,

    This error usually means Azure Device Update thinks an update with the same Provider + Name + Compatibility already exists, even if the version is new. Sometimes old updates aren’t fully cleared or the service caches data, which causes this unexpectedly. Try changing the update name slightly or modify the compatibility (model/manufacturer). You can also delete older updates with the same details and wait a few minutes before retrying. If it still fails, it’s likely a backend issue—retry later or raise a support ticket with the Trace ID.
