Goodevening Arturo,
Maybe you can try starting the server with $sudo systemctl start neo4j. And then login with $cypher-shell or with your browser localhost:7474.

Yours kindly
Omer

Thank you Omer,
I think I could start neo4j on the server, but I couldn´t acces with the browser. I can´t reach the page.

What I see when I start Neo4j throgh the console is this:

/home/ubuntu$ neo4j start
/usr/share/neo4j/bin/neo4j: line 372: /var/run/neo4j/neo4j.pid: Permission denied

I am not sure if the way you start the server is correct or not. There are still some error etc.

For me I would take a look at the steps from this guide:
How To Install and Configure Neo4j on Ubuntu 20.04 | DigitalOcean.
This is based on systemd.

Yours kindly Omer
