This is something I'm working on doc for, but it sounds like you're practically there!
What are the error messages in your log files?
My bet -- and either way you're going to need to do some of this -- is you need to tweak your configuration. In this file:
Locally open it and edit it, changing the last 3 properties listed. You'll need to update the URL to whatever appspot URL you have, and you probably want to disable whitelisting as well.
Whitelisting means only users who emails end with the local domain (in the default file, @
google.com) can access the server. Other users get rejected, unless they're in the DB as whitelisted users.
Feel free to reply back with problems, or if you want to take it offline you can email me directly. AFAIK you're the first person setting up their own server so I don't mind helping out if you can't figure anything out... and it'll help me make sure I document the stumbling blocks when I write up the doc on launching a server.
Thanks!
