Blazor Routing Error

Describe the bug

As shown in the attached screenshot I'm using routing:

@page "/addbrand/{BrandId:guid}"

When I refresh the url https://localhost:44379/addBrand/1abc52f3-c371-4566-847d-1a986f093396 this lead to error 400 Failed to load resource as the url of balzor negotation changed to https://localhost:44379/addBrand/_blazor/negotiate?negotiateVersion=1 instead of
https://localhost:44379/_blazor/negotiate?negotiateVersion=1

https://localhost:44379/addBrand/_framework/blazor.server.js instead of
https://localhost:44379/_framework/blazor.server.js

and this happened to all of links in _host.cshtml file.

Got Exceptions? Yes, browser console log:
[2020-03-23T21:57:35.846Z] Information: Normalizing '_blazor' to 'https://localhost:44379/addBrand/_blazor'.
