I have the same problem. Here’s what the top of the documentation page looks like for SonarQube running on a server in my network:
Notice that there’s no grey box.
When I go to the Online Documentation of SonarScanner for .NET then the grey box does appear:
Please have someone look at it because I’m getting errors in the Chrome console:
http://10.250.0.9:9000/images/info.svg Failed to load resource: the server responded with a status of 404 ()
http://10.250.0.9:9000/images/exclamation.svg Failed to load resource: the server responded with a status of 404 ()

Have the server send the header with a valid value, or, if an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

The build version of the SonarQube community server I’m testing on is 188.8.131.52792.
With best regards,
