Power BI Gateway looses Service Principal credentials
Hello,lbendlin ,thanks for your concern about this issue.
Your answer is excellent!
And I would like to share some additional solutions below.
Hello,Anonymous.I am glad to help you.
Based on your description, I think there is merit in what lbendlin is proposing.
According to the official Platform workflow, when a user accesses a series of Microsoft products, it involves authentication and authorization methods for different types of applications. Generally it involves the token authentication process.
As for the token lifecycle, the official documentation also describes it, mentioning that it is typically 60 minutes to 90 minutes (about an hour).
When the token life cycle is over. It will expire and need to be reapplied.
And for your description and expiration time is also similar to the official description.
This kind of problem is not only for Power BI, in fact, for most cases, token expiration is an unavoidable problem. I hope you can understand, of course, for the gateway connection and the service subject permissions are also you need to check the place, sometimes the change of permissions will lead to connection problems.
Here is the relevant documentation to help you.

Hello Anonymous,
The access token lifetime isn't the issue here. I understand that Power BI should use the Client ID/Secret pair to obtain a new access token once it expires. It worked for weeks. All of the sudden it doesn't.
What can be the problem here?
CheersHi,Anonymous.Thank you for your reply.
Thank you for your reply, you can try updating the gateway connection because according to your description, your gateway has a warning triangle error, which generally indicates a problem with the gateway itself or a serious problem with the gateway connection configuration. I noticed that you mentioned that your gateway is not currently being updated and that the issue has not existed since it was first configured, but has been an issue for the last two weeks. If you don't think it has anything to do with expired authentication tokens and you want to make sure that your authentication credentials are correct and not expired, I suggest you update your gateway to the latest version.
I would recommend that you update your gateway to the latest version, even though it is a cloud connection, each new version of the gateway usually fixes some of the known issues and bugs in the previous version. These fixes may directly address connection credential errors you are currently experiencing. New versions of the gateway may contain performance improvements that make the data connection and refresh process faster, more stable, and more compatible.
Also check your firewall for some recent rule changes where there are requests being blocked.
Clear your browser cache and reset your gateway connection to make sure that the authentication information, and the data source you are connecting to are correct. Sometimes network instability or server performance can also affect the successful execution of refresh results, and it is recommended that you check for these cases, although they are unlikely.
You mentioned that this does not happen when using Oauth to complete the SQL connection.
In my opinion, using Oauth is a viable alternative if the problem persists after the above version update and gateway connection configuration.
