Tableau Publishing Error Fix

I'm experiencing a "directory not found or missing file" error when trying to publish a workbook from Tableau Desktop to Tableau Server. The Tableau Desktop is supposed to read a live connection to an Excel file in a shared folder, which is inside Tableau server in C. Both tableau desktop and server are in windows.

Requirements:
- Fix the "error
- Explain the issue and how it fixed
- Ensure proper live connection to the Excel file
- Successful publishing of the dashboard to Tableau Server

Ideal Skills and Experience:
- Expertise in Tableau Desktop and Tableau Server
- Experience with shared folder configurations
- Strong troubleshooting skills for connection issues

I'm looking for someone who can quickly resolve this issue. Please share your relevant experience and approach.
