What are you trying to do, because you arent supposed to be accessing datanode via the web, only thr main graylog server talks to it? ---

There is no web interface of datanode just some api endpoints that only the graylog server talks to. As long as you went through preflight then that connection is already secured. ---

Hi @Joel_Duffield Noted on this I have running graylog-server but how about the message on port 9200? it says authentication finally failed do I need to do something to be authenticated when I access the port? Thanks in advanced 😇 ![image](https://us1.discourse-cdn.com/flex016/uploads/graylog/original/3X/3/0/3077fa5140b94e11e25111cb61b27da28898f6c6.png) ---

When datanode is setup during preflight, it is setup to use certificates it generates as authentication, so the only way to access it is to generate a certificate for 3rd part access whixh yiu can do in the graylog UI ---

Hi @Joel_Duffield Thank you for the info I think there’s nothing I can do on graylog-datanode web since it already managed by graylog-server Have a nice day. ---
