Debugging Rails 3 using RubyMine

I'm using RubyMine to develop a Rails3 application, but I cannot manage to get the debugger working. I always get the following message:

Cannot connect to the debugged process at port 60706 in 10s:

Dumping and destroying process, when the debuggee process is running. You might try to increase the timeout. Killing...

Error Output: Fast Debugger (ruby-debug-ide 0.4.17.beta3, ruby-debug-base 0.11.26) listens on 127.0.0.1:60706

Please try increasing timeout in Settings | Debugger | Ruby | Debug connection timeout

I have of course tried to increase the timeout value, but that does not help. I have no idea how to approache the problem. I cannot see any debug output, error log, ... Any hint would be very 开发者_开发百科appreachiated!

It now works for me, with

• RubyMine 3.1.1 build 103.260
• ruby-debug-ide 0.4.17.beta5
• ruby-debug-base19-0.11.25 (I'm not sure wether or not this is actually used)

It didn't work with .beta3 for me, but works like a charm now (.beta5)

I had a similar problem with RubyMine 5.4 (RubyMine 5.4 debugger times out, but debug console shows connected) no indication of any errors, but the debug connection always timed out. Manual remote debugging on the local system worked, however. It turns out that on my system (Mac OS X 10.8.3) that hostname returned localhost. Running sudo hostname new-name solved the problem and now RubyMine internal debugger works just fine.
