Power BI Report Builder Sign In Error: An error occurred while sending the request
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.

Thank you for the in-depth response. I am waiting on IT to see if step 3 is the issue. Unfortunately the other steps did not solve my problem. I am sure this will be helpful for other community members though!
