Hello @Blau9175
Hello && Welcome
Oh boy, first could you show use what Video you used to make these configurations? Just an idea, I would use Graylog documentations or go the Graylogs YouTube site. If you have done this already it would help stating what you did already.
Since we know nothing about your environment, could you enlighten us how you made these configurations or perhaps show us?
Not sure why you would modify your Graylog service, if you can get into Graylogs Web UI (URL) that means the Graylog service is all good.
Normally Graylog has a user name called " Graylog" and if it was permissions on files and directory’s I would have used “chown” instead of messing around with your service file.
Help us , Help you please look here for better clarity on what we need.
