Kestrel: An anonymous request was received in between authentication handshake requests?

问题

I created an Kestrel Asp.Net core application and tried to host it on a Windows Server (server1). I launch the application using

Browsing http://server1:8008 on server1 works without any error.

However, when browsing http://server1:8008 on a remote machine, it gets the following error?

PS C:\Websites\Portal> .\Blazor.exe --urls http://server1:8008
