You'll need to figure out what is preventing you from accessing it. If
you follow the chain of potential causes from browser to Rails you get
1) Browser->Network -- Can you connect to other sites?
2) Network->Network -- Can you connect to the remote computer with
3) Network->Port 3000 -- Can you connect to port 3000 with something
you know works listening on port 3000? (not mongrel)
4) Port 3000->Mongrel -- Does Mongrel receive the request? Try -B
(debug). What about from localhost->localhost:3000? If you can do
localhost->localhost, but not network->network then you have a firewall
5) Mongrel -> Rails -- Is Rails receiving it and sending a reply?
Check rails log.
6) Rails -> Database -- Is the database getting hit?
Then follow the chain back. Tools that can help you:
* lsof -i -P
* route -n
Let me know if you figure it out.
