Activation failed

I have a free n8n license key code that was sent to my email, but when I try to activate it, I get the following message
Activation failed
Activation key has already been used on this instance
I attempted the activation as soon as I received the code. Does anyone know what’s causing this error or why this is happening??
I appreciate your help and collaboration in advance
I have n8n running in Docker, which runs on an Oracle VPS
Operating system: Canonical Ubuntu
Version: 24.04
Image: Canonical-Ubuntu-24.04-2026.04.30-1
Unit: VM.Standard.E2.1.Micro

@Roberto_Roco_Vera that error usually just means the key already got applied, the activation link in the email registers the instance on its own so you often dont need to enter it again. check Settings > Usage and Plan first, if it says Registered youre already set (folders only show in the Personal space btw, not everywhere). if its still stuck on Community, clear the license and re-enter the key:

docker exec -u node -it <your-n8n-container> n8n license:clear

Hey @Roberto_Roco_Vera, to quickly confirm if it’s already active: go to Settings → Usage and Plan within n8n. If it says “Registered”, your license is already active and you don’t need to enter the code again, the error you saw just confirms that the system already detected it.

If it still shows “Community” (no license), run this to clear and retry:

docker exec -u node -it <your-container-name> n8n license:clear

docker restart <your-container-name>

Then restart the container and enter the key again from the same Settings screen. If the container doesn’t have exactly the name you specified, you can verify the name with docker ps.
