Issue with Ghost after updating

After updating Ghost to 5.30, my site and dashboard hosted with Digital Ocean crashed and ended up with a Bad Gateway 502 error. Then after using Powercycle, rebooting, and using a backed up version of the droplet, I managed to get it to work again. But then after again updating it, the same error occurred. Also when trying to restart Ghost by using ghost restart, it took very long and then came up an error message:

✖ Starting Ghost
A GhostError occurred.

Message: Could not communicate with Ghost
Suggestion: journalctl -u ghost_www-datainwonderland-com -n 50

I did use the suggested code snippet and ended up receiving the following message:
Hint: You are currently not seeing messages from other users and the system.
      Users in groups 'adm', 'systemd-journal' can see all messages.
      Pass -q to turn off this notice.
-- No entries --

I am not sure what can I do to fix my site. My site url is www.datainwonderland.com

Debug Information:
OS: Ubuntu, v22.04.1 LTS
Node Version: v16.17.0
Ghost Version: 5.30.1
Ghost-CLI Version: 1.24.0

Run ghost doctor in terminal and check all are in order.

@thimiraonline I just ran ghost doctor and got the following result:

✔ Checking system Node.js version - found v16.17.0
✔ Checking logged in user
✔ Ensuring user is not logged in as ghost user
✔ Checking if logged in user is directory owner
✔ Checking current folder permissions
✔ Checking system compatibility
✔ Checking for a MySQL installation

But when I go back to my site I still see the same error page.

Run ghost setup and perform ghost setup again.

I just ran the function and got the following result in return:

+ sudo systemctl start ghost_www-datainwonderland-com

Try running ghost doctor to check your system for known issues.

You can always refer to https://ghost.org/docs/ghost-cli/ for troubleshooting.

ghost-mgr@data-wonderland:/var/www/ghost$ journalctl -u ghost_www-datainwonderland-com -n 50

If I can have the ssh access and the ghoat-user logins I can check whats wrong.

Thank you for the offer but I would prefer not to give you that information.

or else if I can have remote desktop login through Anydesk or team viewer, I coukd check what happened. Anyway, I wish you will get a help from another one at here. Have a nice day.

Thank you, the same for you.
