Azure: Cannot connect to remote debugger

Question

I want to use Remote Debugger in Visual Studio 2015 to attach to my site. When I try "Attach Debugger" the azure return: The following error occurred while launching remote debugging: Unable to connect to the Microsoft Visual Studio Remote Debugger name 'XXXX'. Windows authentication was unable to establish a secure connection to the remote computer.

In azure portal I set remote debugging and select VS 2015.

Answer 1

These errors might be related to Local Policies > Security Options > Network Security: LAN manager authentication level. It needs to be set to “Send NTLMV2 response only”. Once this is set then the PC was able to open RemoteApp applications without problems.

To set local policies go to command prompt and type secpol.msc or Administrative Tools > Local Security Policy

Answer 2

Maybe your application is not enabled to use remote debugger.

To enable remote debugger in app service:

1. Go to Azure management portal
2. Select your app
3. Go to settings
4. Go to Debugging
5. Enable Remote Debugging
6. Select your visual studio debugger versión
