I'm getting this error when entering to web interface url:
Server currently unavailable
We are experiencing problems connecting to the Graylog server running on http://127.0.0.1:9000/api. Please verify that the server is healthy and working correctly.
You will be automatically redirected to the previous page once we can connect to the server.
Do you need a hand? We can help you.

如您所见，一切都会正常进行.
As you see everything should work without any problem.
这是netstat显示的内容:
Here's what netstat shows:

我认为问题可能出在该自定义标头中，可能需要Graylog:
I assume problem maybe within this custom header which graylog probably need:
RequestHeader set X-Graylog-Server-URL "http://graylog.example.org/api/"
推荐答案
对于本实施示例，我假设example.org是远程主机，而不是127.0.0.1.在这种情况下，假设需要其他标头是正确的.
根据我的经验，您应该删除api/作为最终用户的Web访问权限
您将需要设置请求标头X-Graylog-Server-URL.例如curl -H "X-Graylog-Server-URL: http://graylog.example.org/" http://127.0.0.1:9000.
Graylog Web代理配置如果您想在Graylog服务器之前设置Web服务器，则可以提供一些很好的信息.很遗憾，在撰写本文时， Docker示例不包括基本的nginx配置
For the implementation example you have given I am assuming that example.org is a remote host rather than 127.0.0.1. In that situation, you are correct in assuming that the additional header is needed.
From my experience you should strip api/ for the the end user web access
You will need to set the request header X-Graylog-Server-URL. eg curl -H "X-Graylog-Server-URL: http://graylog.example.org/" http://127.0.0.1:9000.
Graylog web proxy config gives some good info if you want to setup a webserver in front of your graylog server. It's just a pity that (at the time of writing this) the Docker Examples do not include a basic nginx config
我正在使用kubernetes，必须将以下内容添加到我的入口注释中才能正确吸引流量
I am using kubernetes and had to add the following to my ingress annotation to get traffic in correctly
ingress:
annotations:
nginx.ingress.kubernetes.io/configuration-snippet: |
proxy_set_header X-Graylog-Server-URL https://$server_name/;
