What’s the complete configuration of Graylog and Elasticsearch? What’s in the logs of Graylog and Elasticsearch? What’s the output of the following command: ```auto # netstat -tplen ``` ---

I guess you added the port: firewall-cmd --add-port=9000/tcp --permanent. This requires firewall restart unless you issue two commands: firewall-cmd --add-port=9000/tcp --permanent firewall-cmd --add-port=9000/tcp ---

Hello jaskis, I have tried both. I rebooted the server too. But no change. ---

Looks like the webserver never goes up. You need to look into logs at the time the graylog server was started or restart the server to see the same logs. It will show why it does act this way. ---

These GC times are _extremely_ unhealhty. They should be in the sub-second range but take over 10 seconds in your case. What are the specs of the machine running Graylog? What’s in the logs of the Graylog node? ➡ [http://docs.graylog.org/en/2.3/pages/configuration/file\_location.html](http://docs.graylog.org/en/2.3/pages/configuration/file_location.html) ---

Hello Jochen, I have managed the memory and had a fresh install in new machine. `http://:9000` loads the web interface but i dont know which credentials to use. I tried user:admin and password:(ciphered and deciphered form of root\_password\_sha2 ). It didnot work. Please suggest. Thanks. ---

I assume that you’ve made some mistake when creating the SHA-256 hash of the password. Try again and make sure that the password doesn’t include a newline character (i. e. use `echo -n '...' | sha256sum` and don’t forget the `-n` parameter). ---

Hey Jochen, You were correct. i tried echo -n Hello@123 | sha256sum 99f2bdf9942653ab32d9dfa0b43c72c3fbbb9679450fd965c590c224897b848a - i have copied the whole chiphered to server.conf but it didnt work. Later i tried only with 99f2bdf9942653ab32d9dfa0b43c72c3fbbb9679450fd965c590c224897b848a It is working fine now. Thankyou so much for the help. Regards ---
