Hi, I test install graylog on CentOS and I have error in log and I didn`t know what is wrong in my configuration: WARN [ProxiedResource] Unable to call [http://192.168.1.120:12900/api/system](http://192.168.1.120:12900/api/system) on java.net.SocketTimeoutException: timeout Could they give me an example of a valid config? What correct rest\_listen\_uri and rest\_transport\_uri(rest\_listen\_uri = [http://192.168.1.120:12900/api](http://192.168.1.120:12900/api))? I suspect that error is in this line but I give this from example documentation ---

valid configurations can be found in the documentation and if you followed one of our installation guides you should have a valid, working configuration. ---

Adam, sorry that you have that hard time - but the not present information from your end tend to provoke such a generic answer. The Installation will include a working configuration where Graylog will listen on localhost. The configuration itself include those two settings that are commented and just need to be changed to a non-localhost address or wildcard. > > Without knowing your configuration or your setup nodody will be able to help you. ---
