2. Log in with the root user, or another admin user on the system.
3. Back up the ggRock nginx configuration file:
cp /etc/nginx/conf.d/ggrock.conf /etc/nginx/conf.d/ggrock.conf.bak
4. Open the ggRock nginx configuration file in a text editor:
nano /etc/nginx/conf.d/ggrock.conf
5. Using the arrow keys on the keyboard, navigate down to the grafana configuration section

7. Press <CTRL> + 'X' on the keyboard to save and write the file, pressing the 'Y' key to confirm and save changes.
8. Restart the nginx proxy service using the following command:
