I just installed graylog on a vm with 8GB Ram. i am getting error “We are experiencing problems connecting to the Graylog server running on _[http://127.0.0.1:9000/api/](http://127.0.0.1:9000/api/)_ .

What’s the result of running `curl -s 127.0.0.1:9000`? Also, seeing your `server.conf` and any associated logs from Graylog would help. ---
