SSRS Configuration Error; Invalid PBI Configuration

I got this issue on one of my machines when I installed MSSQL Server 2016 with SSIS, SSAS and SSRS.

SSIS and SSAS is working fine but SSRS does not.

After the installation, I opened the Reporting Services Configuration Manager and leave everything to default. This usually the end of it, but for some reason when opening the Portal, I got this:

When I check the log, the error is

ERROR: Throwing Microsoft.ReportingServices.Diagnostics.Utilities.ServerConfigurationErrorException: Invalid PBI Configuration, Microsoft.ReportingServices.Diagnostics.Utilities.ServerConfigurationErrorException: The report server has encountered a configuration error. ; 

What is Invalid PBI Configuration? And how do I identify the problem?

Thank you in advance.

Took a while to sort this out, but it's a simple fix.

1. Open SQL Server Reporting Services Configuration Manager
2. Click on Web Service URL menu and make sure that the URL's match the ones located in Web Portal URL menu.
3. If they're different, open the rsreportserver.config file (C:\Program Files\Microsoft SQL Server Reporting Services\SSRS\ReportServer) and remove any entries not listed in Web Service URL.
4. Open your web portal ie. and see if it's resolved. If so, all done.
5. If not, click the Encryption Keys menu, in the "Delete Encrypted Content" section, click "Delete".
6. Open your web portal again and see if it's resolved.
7. Locate and update your datasource credentials.
