Ramy,
I have verified I am using correct App ID in Server\Config.json file |
Are you saying that you have added the appId to specific apps config.json (i.e. [intsall dir]\server\apps\[app#]\config.json)?
Or are you talking about the [intsall dir]\server\signininfo.json?
Have you tried to delete the [intsall dir]\server\signininfo.json?
I have never seen the "machine name refused to connect" error can you share a screenshot?
