Mapped Network Drive - Can't access CSV data, "We couldn't authenticate with the credentials..."

[Anonymous]

Hello!

So I've had a version of a Power BI report I've been working on for months. Each version uses the same data sources that I've mapped to my "Z" drive. For some reason all of a sudden, when I've tried to refresh it now throws an error saying "We couldn't authenticate with the credentials provided. Please try again".

I've been using the identical setup to access these CSV files for months. I'm logged into Power BI with my Windows credentials, and when I go to edit the data sources, that is the only login option it gives me - to use my Windows credentials. It won't work with "Use my current credentials" or "Use alternative credentials", where I'm re-entering my creds essentially again.

Is there a different route I should be using to access these files going forward? Thanks!

No, that sounds weird. Did you company perhaps implement MFA? Did you recently upgrade your Desktop? What is the version? File | Options and settings | Options | Diagnostics.

You could check the Issues forum here:

And if it is not there, then you could post it.

Thanks Greg!

The odd thing is I can see mapped network drive and all those files in my File Explorer. If I click to launch one it opens Excel as it should. In Power BI, if I tell it to pull in new data, I can see it via that route as well.

We did implement MFA within the last few weeks, didn't even think about that...good point! It's odd though that I can see and read the data through just about every other mean under the sun still, just not this existing Data Source setting I've had for almost a year now.

We do have Pro accounts for a few of us so I'll open a ticket...thanks for the comments and the heads up!
