Description

### Bug description
After creating an aspnet core project template with Visual Studio 2019 Community Edition or dotnet CLI in linux environment, I have found the following issue:

* In Google Chrome and Microsoft Edge web pages does not load and browser says: ERR_CONNECTION_RESET.
* In Brave browser loads normally the project with SSL eneabled.

**No aditional changes made to the project template**

### To Reproduce
Create a new aspnet core project with VS2019 or with the dotnet CLI as follows:
`
dotnet new mvc -o MvcMovie
`
then open the project and run with F5 or Ctrl + F5 (in VS or VS Code).
