Can't reach local GAE server through my ip

Question

I developing an app with GAE as a back-end, when I run GAE server locally I can reach it in the browser through localhost:8888 but when I try to reach from an external device on the same wifi network, with my <my local ip>:8888 I get no response. I was always using this way do debug my apps and back-ends and suddenly it stopped working?

Found the answer at last, add 0.0.0.0 address to the servers run arguments. As described here : Can access AppEngine SDK sites via local ip-address when localhost works just fine and a MacOSX
