OAuth2 credentials become invalid after successful update (Data Source Settings)

[abmate]

Hi, folks!

Credentials for one of the Data Sources that connects to Kusto become invalid after about an hour or so showing this message:

Then, I go ahead to Authentication Method, click on "Edit Credentials", select OAuth2 again, click on "Sign in", select my account from the pop up window, and then hit "Apply". After that, the Data Source Settings show connection successful.  My reports refresh correctly either on demand or scheduled.

However, after some time, reports start failing to refresh again because the credentials are no longer valid in which case, I have to repeat the above steps again. This started to happen on March 7th, where all of our reports that depend on this data source started to fail during scheduled refresh. 

Why my credentials become invalid?  Any help is greatly appreciated.

Abe.

Hi @abmate 

What I find when using Kusto is to rather use the other authentication methods with keys.

It appears that the accounts token is expiring every hour.

Thanks, @GilbertQ !

Unfortunatelly, given my organization security policies it seems I cannot use the other authentication methods (i.e. Basic or Windows fail to connect for me). OAuth2 goes through two factor authentication first and that seems to work until credentials become invalid again 😞 

This used to work fine until a few days ago. 😞

Hi @abmate 

I would chat to your network/2FA admin to see if they have made any changes to your account that could be causing this issue?

Thanks, Gilbert!

So, while I was ready to figure out who my network Admin was, the issue went away. So I have no idea what went wrong and how it got fixed. It lasted 3 days.
