Install odoo13 on Contabo

I installed Odood 13 on Contabo servers (Ubunto 20.04) by executing the following commands through ssh:

sudo wget https://raw.githubusercontent.com/Yenthe666/InstallScript/13.0/odoo_install.sh
sudo chmod +x odoo_install.sh
./odoo_install.sh

Then a message appears indicating that the installation is complete:
Done! The Odoo server is up and running. Specifications:
Port: 8069
User service: odoo
Configuration file location: /etc/odoo-server.conf
Logfile location: /var/log/odoo
User PostgreSQL: odoo
Code location: odoo
Addons folder: odoo/odoo-server/addons/
Password superadmin (database): ************
Start Odoo service: sudo service odoo-server start
Stop Odoo service: sudo service odoo-server stop
Restart Odoo service: sudo service odoo-server restart

But after opening the browser: http://195.88.87.62:8069/

A message appears:
This site can't be reached195.88.87.62 refused to connect.
Try:

Needed to reinstall Odoo 13 on the server?
