Issue with Migrating On-Premises Gateway (Personal Mode)

[jrsimmon]

I needed to migrate my On-Premises Gateway (Personal Mode) to a new PC. I downloaded the gateway software to the new PC and successfully installed it. The gateway says that it is online and ready to be used on the new PC. When I attempt to refresh a connection in the service it says the connections is offline and provides the following error:

Error code: UnknownError
Connection error: Unknown error
Cluster URI: https://api.powerbi.com

:
undefined: Received error payload from gateway service with ID 121840: Error when verify signature connection the target data source.

Thanks in advance!

Hello @jrsimmon ,

I recently wrote a blog about On-Premises Gateway, which might help clarify any missing points. You can check it out here:
How to Set Up Power BI On-Premises Gateway Connections

In my opinion, the error might be due to the new PC not being active. If it is active, could you try searching as shown in the image below?

If the issue persists, there might have been a misconfiguration during the installation process. Let me know how it goes.

Kind Regards,

Hi @jrsimmon 

To resolve the gateway issue:

1. Revalidate Credentials: In Power BI Service, go to Settings > Manage Gateways and re-enter the data source credentials.
2. Check Gateway Mapping: Ensure the dataset is linked to the new gateway in Gateway Connection settings.
3. Verify Network: Confirm the new PC can access https://api.powerbi.com and other required endpoints.
4. Update Gateway: Install the latest version of the On-Premises Gateway (Personal Mode).
5. Check Certificates/Paths: Ensure required certificates or file paths are correctly configured on the new PC.
6. Re-register Gateway (Optional): If needed, unregister and re-register the gateway using the migration key.
7. Test Connection: Test the connection in the dataset settings.

If the issue persists, enable gateway logs for debugging or contact Microsoft Support.

I had to re-enter all credintials for all data sources.
