Ghost cms in google cloud use bitnami. Domain down

I installed nginx on my Bitnami ghost Linux Devian 11 x86-64. After that I made some changes in the default file. Now I am trying to start it but I am getting following error:


admin@ghost-1-vm:~$ sudo /opt/bitnami/ctlscript.sh restart
Restarting services..
Job for bitnami.service failed because the control process exited with error code.
See "systemctl status bitnami.service" and "journalctl -xe" for details.
