Microsoft® Visual Studio® is unable to start debugging on the Web Server.
This issue occurs when Visual Studio attempts to start debugging on IIS 7, IIS 8, or IIS 10. This issue can occur if you are using either the ASP.NET Development Server (ASPDesign) or the ASP.NET Development Server (IIS). The ASPDesign server is not supported in IIS 7 or IIS 8 and is not recommended for use with IIS 10.
Visual Studio Unable To Start Debugging On The Web Server
This error indicates that Visual Studio cannot attach to your web application. This can occur if another debugger is already attached, or if the application is not running. To resolve this issue, you can either remove any other debuggers that are attached to the web application or start the application in debug mode.
Unable to start debugging on the web server you do not have permissions
This error indicates that Visual Studio cannot attach to your web application because it does not have proper permissions. The most common cause of this problem is that you don’t have rights to access IIS (Internet Information Services) or ASP.NET files.
You can resolve this issue by granting yourself full control over all files in your website’s root directory (for example: C:\Inetpub\wwwroot\) and then restarting Visual Studio with Administrator privileges.

When you try to debug a web application, you may receive the following error message:
Unable to start debugging on the web server a debugger is already attached.
To resolve this issue, close any other instances of Visual Studio that are connected to the same remote computer as the one that you want to debug.
Unable to start debugging on the web server a debugger is already attached
If you are trying to debug an app that has an existing remote debugger attached, you will get this error message. To resolve this issue, you need to stop debugging and then restart it.
You can also avoid this error message by using the Visual Studio 2019 command line interface (CLI) instead of the Visual Studio IDE. For more information, see Debugging ASP.NET Core applications in Visual Studio 2019 on Linux or macOS.
I am able to run the project with no issues and I am able to debug it.
I have tried:
1) Uninstalling and reinstalling the extension.
2) Changing the server name and port number in options.
3) Changing the type of connection between the server and client from ‘Remote’ to ‘Local’.
Remote Debugger Windows 10 – Basic Tutorials for Beginner Developers. In this video we will learn how to debug our application using remote debugger in windows 10 using Visual Studio 2019. Remote Debugging is the process of controlling your code from another computer.
Unable to start debugging on the web server a debugger is already attached
This is most commonly caused by multiple instances of Visual Studio being run at the same time. To resolve this issue, close all instances of Visual Studio, then restart your computer and try again.
Start debugging on the web server you do not have permissions
Make sure that you are a member of the Administrators group on your computer and that you are able to log in as an Administrator user. If you are unable to log in as an Administrator user, contact your system administrator or the person who installed Visual Studio for assistance.
Unable to start debugging on the web server visual studio 2019
The remote debugger is a feature in Visual Studio Enterprise 2019 and Visual Studio Team Services (VSTS).
You can use the remote debugger to debug web sites hosted on other servers.
If you’re having trouble connecting your project to a remote target, here are some things to try:
Unable to start debugging on the web server a debugger is already attached.
Make sure that there isn’t an existing instance of Visual Studio or Visual Studio Code running with the same configuration as your project. You can check this by looking at the Status Bar at the bottom of your window, where it should say “Running” if there is an existing instance. If that doesn’t work, close all instances of Visual Studio and try again.
Remote debugger
Remote debugging is an essential part of any modern web development workflow. When a browser is used to debug a web application, it must connect to the IDE through a reverse connection that allows data to be exchanged between the client and server.
In Visual Studio 2019, remote debugging is available for ASP.NET Core. You can use it to debug your application running on Linux, macOS or Windows from your local machine (Windows).
There are two ways to setup remote debugging:
Using Docker for Mac or Windows and Visual Studio Code (or another code editor) running on macOS or Windows: in this case, no additional configuration is required on the machine running Docker for Mac/Windows;
Using Docker Toolbox on Linux (or another code editor): in this case you need to configure an SSH tunnel so that Visual Studio Code can reach your Linux machine on port 22;
Remote debugging is a feature of Microsoft’s Visual Studio IDE that allows developers to connect to and debug code running on a remote machine. This can be especially useful when working with web applications, as it allows you to debug your client-side code on the server, in addition to your locally run application.
