license activation

Hello n8n Support,

I am self-hosting n8n on a VPS using Docker (container name: root-n8n-1).
My activation key returns the error:
“Activation key has already been used on this instance.”

The container is clean (no license.json and no .n8n-instance-id file).
Please reset/unlink my activation key so I can use it on this server.

Thank you.
