Hook response always time-out

I always get this

{"name":"hook-response/bouncer/0","data":"{\"code\":\"ETIMEDOUT\",\"errno\":\"ETIMEDOUT\",\"syscall\":\"connect\"}","ttl":"60","published_at":"2015-07-02T12:12:17.875Z","coreid":"undefined"}

I can fire POST Requests without any problems from my MAC and web-hooks with requestBin work as well. only the mine doesn’t now the error given is not very helpful as I suspect it’s not really a timeout problem. When and how is the timeout error generated?
