Web Service URL not working and returns error

Hi everyone,

I am attempting to get the developer version of the Power BI Report Server up and running for testing and evaluation for my team. I am having issues with getting the Web Service URL (and Web Portal URL) to work properly as noted in all the different tutorials I have read and watched.

Currently when I click on the link provided to me by the Power BI Configuration Manager, it opens up Chrome and after a short while returns the following error message:

An internal error occurred on the report server. See the error log for more details. (rsInternalError) Get Online Help. Object reference not set to an instance of an object.

I’m a bit frustrated as to what I am missing to get this to work as the tutorials all make it seem very easy with very little troubleshooting for any common errors one may encounter.

Below is more context about my problem:

• I have installed SQLExpress onto my machine
• I am part of a organization with an assigned user account, pw, and local administrative privileges to machine.
• I am working from home and not connected to

Within the Power BI Reports Server configuration manager, I have the following settings:

• Product version is 15.0.1102.777 (January 2020 edition)
• Service Account tab
  • Use built-in account: Virtual Service Account
    • Should I be using the network service option?
  • Use another account: (none)
    • Should I use my organization account and pw instead?
  • Web Service URL tab
    • Virtual directory: ReportServer
    • IP Address: all assigned (recommended)
    • TCP port: 80
    • HTTPS certificate: (not selected)
    • HTTPS port: (none)
  • Database tab
    • No current report server database configured. I do not have a separate SQL server running that I can connect the report server to. I assume that the Power BI Report Server will take care of storing the data. Please let me know if this assumption is wrong.

Is there something I have not installed, setting that I have overlooked, or something I need to set up on my machine in order for this to work?

Someone please help! 😊
