Unable to Connect to Web Server
When you start Visual Studio, it tries to connect to a web server. This can happen when you start the IDE or when you try to build a project. If the IDE cannot connect to a web server, an error message will be displayed in the Error List window. This is called “Cannot Connect To Web Server” error.
If you get this error when you try to build your website, it could be because of several reasons.
The following are some of the most common causes:
1. The project may be missing a reference.
2. The project may be using an old version of the .NET Framework or Visual Studio.
3. The project may not have been opened within Visual Studio for some time, so the current configuration information for the project has become out-of-date.
4. If you installed the Web Tools SDK v12 under C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\Common7\IDE\Extensions\Microsoft\Web Developer Tools 12 (Beta)\Tools\WebDeployment, that folder structure may not exist if you installed Visual Studio 2019 in an alternate location such as C:\Program Files (x86)\Microsoft Visual Studio 19\Professional Edition 2019\.

Visual Studio Unable To Connect To Web Server Iis Express
I have a problem with Visual Studio. I am using Visual Studio 2019, and I tried to connect to my web server (IIS Express). The result is that it says “The remote server returned an error: (401) Unauthorized.” And then it gives me two options: “Retry” and “Cancel”. So I choose retry, then it says “The remote server returned an error: (401) Unauthorized.” again, so I choose retry again, then it says “The remote server returned an error: (401) Unauthorized.” again, so I choose retry again, then it says “The remote server returned an error: (401) Unauthorized.” again…And so on.
