Clearly you did not follow any advice we gave you.
Why are you using wordpress manager ?
Are you using docker ?
For example How to install & setup Ghost on Ubuntu 20.04 or 22.04 it states
Before getting started you should set up a working DNS A-Record from you domain, pointing to the server’s IP address. This must be done in advance so that SSL can be configured during setup.
This means you just create a website for your domain and that is it.
Then Install Ghost-CLI read the docs on how to do this
Then skip the install Ghost process as Ghost comes with NGINX and SSL setups of its own this I can see you knew how to get around this. Just to highlight it for the community its usually running:
$ ghost setup --no-setup-nginx --no-setup-systemd --no-setup-ssl --no-start
Reboot your server or just run systemctl restart lsws
Now for good measure install PM2 read the tutorials I highlighted above to know what is wrong with your installation if any. With ghost cli you will hardly ever need pm2 because they all monitor the app and can restart, start and stop it.
