I'm getting a strange error: 'Failed to enable remote debuggingException from HRESULT: 0x89710023' while I'm trying to debug remotely Azure Website. I'm using VS2013 with Azure Tools v.2.2. There are a lot of people who are getting this error here http://blogs.msdn.com/b/webdev/archive/2013/11/05/remote-debugging-a-window-azure-web-site-with-visual-studio-2013.aspx but there is no working solution.
Resolved
I've managed to resolve this as installed Azure Tools 2.2 on a new machine with fresh installed VS 2013. Not sure what caused the issue.
The error isn't very forthright.
I found the answer from Twitter https://twitter.com/martinhelgesen/status/410363288132657152
Basically just open up ports 4016 and 4018 and things should work.
I found that if my site name contains a - sign, the remote debugger will not work. The remote debugger worked when I switched to a site name without the '-' sign.
