尽管进行了所有设置，但出现以下错误
Despite all the settings, I am getting following error
System.Runtime.InteropServices.COMException (0x89710023): Unable to connect to the Microsoft Visual Studio Remote Debugger named 'essamplepoc2.azurewebsites.net'. The Visual Studio 2017 Remote Debugger (MSVSMON.EXE) does not appear to be running on the remote computer. This may be because a firewall is preventing communication to the remote computer. Please see Help for assistance on configuring remote debugging.

推荐答案
问题已解决.我们必须在公司防火墙上打开VS 2019的出站端口4024，VS 2017的出端口4022和VS 2015的出端口4020.
The issue is resolved. We had to open outbound ports 4024 for VS 2019, 4022 for VS 2017 and 4020 for VS 2015 on corporate firewall.
