N8n license key activation problem on self-hosted Hostinger VPS

I have n8n self-hosted in a Hostinger VPS and already received a license key. But when I enter to Settings > Usage & Plan > Enter activation key, I receive the next message:

Activation failed

Activation key has already been used on this instance
Activation key has already been used on this instance

Any tip to solve the problem? OS is Ubuntu 24.04

Hey @IbarCarty

Try running

docker exec -u node -it [n8n-container-name] n8n license:clear

Or in docker desktop run this in the container terminal

n8n license:clear

Sorry, I’m new at this. I don’t know which is my container name. I know which is my host name.
When I enter that command on the terminal it says: “Error response from daemon: No such container:”
How can I look for my container name?

@IbarCarty

Do you have docker desktop , it will show in the container page
Or in your pc terminal type : docker ps
And look for the container using n8n image
