Dataflow - Token Expire Error for Dataflow connections

Hi MookhomH ,

Please try below steps:

1. Refresh Credentials:
- Go to the Power BI Service.
- Navigate to the workspace where your dataflow is located.
- Select the dataflow, then go to `Settings`.
- Under `Data source credentials`, update or refresh your credentials.

2. Check Dataflow Timeout Settings:
- Ensure that the timeout settings for your dataflow are not causing the token to expire prematurely.
- You can adjust these settings in the dataflow options if necessary.

3. Reauthenticate:
Sign out of Power BI Service and sign back in to ensure your authentication token is refreshed.

4. Clear Browser Cache:
Sometimes, browser cache can cause issues with web services. Clear your browser cache and cookies, then try again.

5. Try a Different Browser or Incognito Mode:
Attempt to connect the dataflow using a different web browser or an incognito/private browsing window to rule out any browser-specific issues.
