This is a known limitation when connecting NAS drives in Power BI — mapped drives like O:\ won't work directly because Power BI runs under a different context. Here's what usually helps:
-
Use the UNC path instead of drive letters:
For example, \\100.11.11.1\sharedOne instead of O:\ -
In the credentials section, try:
-
NASNAME\Username or DOMAIN\Username
-
Avoid LOCALMACHINE\Username unless the NAS is part of that machine’s domain.
-
-
Make sure the gateway (if used) has access to the NAS path directly — the connection must succeed from the gateway machine’s perspective.
-
As a last resort, if authentication fails despite valid creds, test mapping the NAS to a folder path using a script with net use and run Power BI as admin.
