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
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?
