DataMiner Deployment Error: “UnauthorizedImpersonatedDataMinerUser” After Fresh Installation

Solved156 views6th August 2025

Hello!

After installing DataMiner and connecting it successfully to the DataMiner Cloud Platform, I encountered a frustrating issue during my first attempts to deploy protocol updates and drivers. Here's a walkthrough of the error, analysis, and some potential resolutions that might help others facing the same situation.

{
"errorMessage": "Unexpected exception occurred",
"exceptionMessage": "StatusCode: UnauthorizedImpersonatedDataMinerUser, DebugMessage: Could not create a connection for user DOMAIN\\Username, DmaId: XXXXX",
"stackTrace": "... at ArtifactDeployer.Deployer.Implementations.DataMinerFileUploader.UploadFromFileAsync ..."
}

Thank you!

hard to say just from this abstract of the stack trace – but it seems the (domain) user may not have authorization for CloudConnected operations.

I'd check if the user is defined for ADMIN tasks in the "ADMIN" section of "dataminer.services" – perhaps if the email is the same where using a domain account.

Will try to add s screenshot for visual reference

Hi Alberto,

thank you for your Answer.

This was my solution:
https://docs.dataminer.services/dataminer/dataminer_services/Advanced_config/Disconnecting_from_dataminer.services.html

But for all reading this, handle with care...
