Setting ghost blog on digitalocean and redirecting it into other server on subdirectory as /blog

Hey, I would like to setup ghost on digitalocean and then redirect it into my second server as https://kasacja-aut.pl/blog (this is proxied via cloudflare) when I setup everything in ghost this accurs in logs, :

My sites-enabled setup:

Does anyone have idea whats wrong?

My sites-enabled setup:

The error tells No such file or directory.

It means the mentioned file, in this case, node is not existent. How do you install Node.js?

Do you follow How to install & setup Ghost on Ubuntu 16.04, 18.04, 20.04 or 22.04 guide?

Ok, I found the issue.

Can someone tell me if my nginx configuration is set correctly?
