When I tried to start and input I got an error about the input not being able to start. The popup suggested I check my error logs, here is what I see:
2017-10-23T10:47:51.826+01:00 WARN [ProxiedResource] Unable to call http://VMExternalIP:9000/api/system/metrics/multiple on node <0e3dcc02-a09a-4a7f-b9eb-13ff286b89f8> java.net.SocketTimeoutException: connect timed out
I have provided what I deem to be the relevant parts of my config.
rest_listen_uri = http://InternalP:9000/api/ rest_transport_uri = http://ExternalIP:9000/api/ web_listen_uri = http://InternalIP:9000/
I believe that Graylog can connect to its external IP, however I am not 100% sure. Can anyone suggest how I would test this?
