Graylog (docker) + Apache2 Reverse Proxy -> Blank page

Graylog Central (peer support)
1

Hello,

using the default docker-compose template from http://docs.graylog.org/en/3.0/pages/installation/docker.html and the Apache2 HTTPS Reverse Proxy configuration from http://docs.graylog.org/en/2.4/pages/configuration/web_interface.html and I get a blank page with “Graylog Web Interface”. Already tried different parameters for URI_ENDPOINT and so on.

                ProxyPassReverse http://127.0.0.1:9000/
        </Location>

Not sure what is wrong. Atleast I get a blank page and no connection error.

Changed

RequestHeader set X-Graylog-Server-URL "https://graylog.example.org/api/"

to

RequestHeader set X-Graylog-Server-URL "https://graylog.example.org/"

and

      - GRAYLOG_HTTP_EXTERNAL_URI=http://127.0.0.1:9000/

to

      - GRAYLOG_HTTP_EXTERNAL_URI=https://graylog.example.org/

fixed it for me.
