Graylog plugin: Blank Page

[ZeFritz]

Hello,
after installing the Graylog plugin from the community plugins via the WebUI of my TrueNAS installation (13.0-U3.1), I’ve tried to open the Graylog UI via http://xx.xx.xx.xx:6000
But all I’ve got was a totally blank page, on Safari as well as on Chrome.
Trying to check the server.conf file in the default location, as mentioned on https://go2docs.graylog.org/5-0/setting_up_graylog/default_file_locations.html, only revealed that in the /etc directory there wasn’t even a subdirectory „graylog“, not to mention /etc/graylog/server/server.conf.
The log files in /var/log didn’t gave any clues, either. And /var/log/graylog-server didn’t existed. Creating it and re-starting the jail, /var/log/graylog-server stayed empty, and the actualised log files still didn’t gave any clues.
I’m at a loss what to check next, and searches in the internet have been fruitless.
Some help would be appreciated.

The default port, unless you changed it, is 9000, not 6000.

Trying to check the server.conf file in the default location, as mentioned on https://go2docs.graylog.org/5-0/setting_up_graylog/default_file_locations.html, only revealed that in the /etc directory there wasn’t even a subdirectory „graylog“, not to mention /etc/graylog/server/server.conf.

The graylog files are in /usr/local/etc/graylog/

The log files in /var/log didn’t gave any clues, either. And /var/log/graylog-server didn’t existed.

The log files are in /var/log/graylog/

If you read the popup after the install finishes, these location are mentioned. Also, within the log when you first start the plugin, you will find the username and password. Mine shows:
It seems you are starting Graylog for the first time. To set up a fresh install, a setup interface has been started. You must log in to it to perform the initial configuration and continue. Initial configuration is accessible at 0.0.0.0:9000, with username 'admin' and password '**********'. I wish they would add this to the popup or post-install notes. Good luck
