3744067 - "The specified file server whitelist does not exist, or is not a file" error when creating a File Server connection in SAP Analytics Cloud

Symptom

When trying to create a connection to File Server in SAC, the following error pops-up: "Access to the path specified in the connection is not permitted."
The Catalina error logs indicate that the specified file server whitelist does not exist or is not a file with the following error: "The specified file server whitelist does not exist, or is not a file"

Environment

SAP Analytics Cloud 2026.2.10

Reproducing the Issue

Attempt to create a SAC File Server import connection.
Notice the "Access to the path specified in the connection is not permitted." error.
Collect the Catalina logs.
Observe the "The specified file server whitelist does not exist, or is not a file" error.

Cause

The whitelist path was set via the Apache Tomcat GUI tool, in the "Java Options" tab. However, the paths were incorrectly pointing to a folder instead of a .txt file. This was causing the Tomcat to throw the error indicating that the specified path is not a file.

Resolution

Update the whitelist path to point to a file, e.g., "P:\\SAC\\Import\\whitelist.txt".
Use UNC paths instead of mapped drives, e.g., "\\Server\\My Share\\SAC\\Import\\whitelist.txt".
Restart Tomcat after making configuration changes.
Ensure the user running Tomcat has explicit read/write permissions to the folder.
