Any idea how i can fix this?

Welcome to Ghost!

Did you take the suggestion to do what Ghost said? That may get you some useful debugging info. (Run the ghost start command again first.)

Your node and Ghost version look fine, and you’re on Ubuntu, so that’s good. Is this a typical install with the Ghost CLI?

Is this the first error message? Or is there another one up above the debug information?

Since you haven’t posted your config.production.json file (MINUS the passwords) or told what changes you made by following a tutorial, I’m not sure anyone can provide more help. Please update the post with as much info as you can share if you’d like help!
