I’m about at my wits end. I configured Graylog2 on CentOS 7 using: ttp://docs.graylog.org/en/2.3/pages/installation/os/centos.html & [http://docs.graylog.org/en/2.3/pages/configuration/web\_interface.html#configuring-webif](http://docs.graylog.org/en/2.3/pages/configuration/web_interface.html#configuring-webif) My old graylog server crashed and I rebuilt it with a larger storage capacity. On my test environment Graylog will connect and display fine on a system (this did have internet access) and once moved to our DMZ environment with zero internet access and no DNS, I can’t even connect to the Graylog Webpage. The IPs were changed from 192.168.1.150 to (fake public IP range we own) 150.150.150.150. If do a Curl http://local\_IP:9000/ the error is Cur: (7) Failed to connect to local\_IP:9000; Connection refused. If I set the local IP to 127.0.0.1 and enter a CURL command. I get the My web\_listen\_uri: [http://0.0.0.0:9000/api/](http://0.0.0.0:9000/api/) My rest\_listen\_uri: [http://0.0.0.0:9000/](http://0.0.0.0:9000/) It works fine on my test environment, but fails in our dmz network that doesn’t have dns/internet access and it’s worked before with smaller capacity. What am I missing? ---

Solved. Patience is the name of the game? No idea why, but it works now after not doing a thing. ---
