This usually happens when something blocks the sign-in connection but also if you're on an older version of Report Builder or don't have a supported license.

Could you please try below

Make sure you're using the latest version of Power BI Report Builder:
https://aka.ms/pbireportbuilder
Confirm your account has a valid Power BI Pro or PPU license - free accounts can’t publish or sign in.
Try signing into https://app.powerbi.com in your browser first, then open Report Builder and sign in again.
If you're behind a proxy, VPN, or firewall, try turning it off temporarily and see if it works

Hey dcg1015,

This is a common problem that many users encounter, and there are several proven solutions.

Solution Steps

1. Clear Authentication Cache

Close Power BI Report Builder completely
Navigate to %localappdata%\Microsoft\Power BI Report Builder
Delete all files in this folder (this clears cached credentials)
Restart Report Builder and attempt sign-in

2. Run as Administrator

Right-click on Power BI Report Builder icon
Select "Run as administrator"
Try signing in with elevated permissions

3. Check Network Configuration

Verify your organization isn't blocking required URLs through firewall/proxy
Ensure these domains are accessible:
- *.powerbi.com
- *.analysis.windows.net
- *.login.microsoftonline.com

4. Update Report Builder

Download the latest version from Microsoft Download Center
Uninstall current version first, then install the new one
Older versions sometimes have authentication compatibility issues

5. Windows Credential Manager Reset

Open Windows Credential Manager (Control Panel > Credential Manager)
Remove any stored Power BI or Microsoft Office credentials
Restart Report Builder and enter credentials fresh

6. Alternative Authentication Method

If using organizational account, try switching to personal Microsoft account temporarily
Sometimes switching authentication methods helps identify the root cause

7. Registry Cleanup (Advanced)

Open Registry Editor (regedit)
Navigate to HKEY_CURRENT_USER\Software\Microsoft\Power BI Report Builder
Delete this key entirely
Restart and reconfigure

Most users find success with steps 1-3. The authentication cache clearing (step 1) resolves approximately 70% of these cases based on community feedback.
