Answered: Error during WebSocket handshake
I am having a problem following the tutorial for the Todo app using sencha.io. After I have included the sencha.io sdk and try to reload the page I should see a login page, but I do not and I am getting this error: Error during WebSocket handshake: 'Connection' header value is not 'Upgrade'.
I posted this issue in the tutorial post itself but I was directed to post my issue here. One idea as to why I am getting this error was that because the current version of Sencha.io uses Websockets which is a newer technology and it might be possible that not all network environments support it. Also many firewalls and proxies may prevent them from establishing a connection.
Since I am very new to Sencha Touch and even newer to using Sencha.io I have no idea as to where I should even start to debug this problem. So if anyone could shed some light on this issue it would be very much appreciated.
