How to restart Portainer on Ubuntu? – Docker

I am on Ubuntu 22 have just installed Docker and Portainer, when I try to access it via IP:9000, I get a timeout message:

"New Portainer installation
Your Portainer instance timed out for security purposes. To re-enable your Portainer instance, you will need to restart Portainer.

For further information, view our documentation."

At portainer.io forum people recomend the a command:

sudo docker start portainer

No result.

Also repeating the commnad:
sudo docker run -d -p 9000:9000 –name portainer –restart always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer

Only got a message on my SSH saying I would install another portainer, which I don’t need.

On youtube tutorials, they open the IP immediately after installation, whithout the timeout bug.

Any clue?
