how to remotely Debug Azure web app slot

I have used Azure remote debugging of my web apps very effectively. However, in prod, we are using deployment slots and our staging slot is causing some errors and needs to be debugged. Some of my team members tried to remotely debug it, but when they attached, it produced the following error:

System.Runtime.InteropServices.COMException (0x89710023): Unable to connect to the Microsoft Visual Studio Remote Debugger named 'mysite123prod-staging.azurewebsites.net'. The connection with the remote endpoint was terminated.

at Microsoft.VisualStudio.Debugger.Interop.Internal.IDebuggerInternal120.ConnectToServer(String szServerName, VsDebugRemoteConnectOptions[] pConnectOptions, CONNECT_REASON ConnectReason, Int32 fIncrementUsageCount, IDebugCoreServer3& ppServer) at Microsoft.VisualStudio.Web.Azure.MicrosoftWeb.Operations.RemoteDiagnosticsSessionBase.ConnectToServer(String site, String user, String password)

Can this be done in Azure and if so, how?

There could be many possible reasons for the issue.

  • You might have turned off the firewall on your machine.
  • Check that if the Remote Debugging on the Azure Web App is set to ON in the portal and has the correct Remote Visual Studio version.
  • If this worked well before, you could delete the web app and re-publish it again. You may also want to open the below ports and check if that solves your issue. enter image description here

For more details, refer to Configure the Windows Firewall for Remote Debugging and Remote Debugging Errors and Troubleshooting.
