Most likely: The magic link is being blocked by a spam filter or corporate firewall, and your license key is throwing an error because it is still “locked” to a previous installation (or test instance).
try:
• Check your Spam/Promotions folder specifically for emails from n8n.io.
• Whitelist the domain n8n.io if you are behind a corporate firewall (e.g., Mimecast/Proofpoint).
• Reply with the exact email address you used and your License Key so n8n team can reset the activation on their end.
• Deactivate the license on your old instance (if accessible) via Settings > License > Deactivate.
Quick questions:
• Did you recently re-installed n8n or migrated to a new server?
• Are trying to log into the Cloud (app.n8n.cloud) or a self-hosted instance?
Hi @Kelly_Pienaar Welcome!
I guess you are trying to validate your self hosted n8n instance using a verified community license , you can always resend that license key and also for checking that is your n8n registered or not just visit settings > usage & plans and there will be able to see ‘Registered’ if it is registered already, hope this helps.
I will respond to the license activation , i have a local server instance and i wanted to add my account to this and i am trying to create a new account for this , and i am not behind a firewall
You likely re-installed n8n (re-created the Docker container) or moved to a new server without copying over the /home/node/.n8n folder. This generated a new Instance ID.
The license system sees Key X is already active on Instance ID A, but now Instance ID B is trying to use it. It blocks the attempt to prevent piracy.
You must email help@n8n.io with the following details:
Subject: “License Reset Request - Self Hosted”
Body: “I re-installed my self-hosted instance and my license key is now locked. Please reset key: [your key].”
hopefully they usually reset these very quickly.
if this didn’t help , you can reset the owner account via the command line without needing an email: docker exec -it n8n n8n user-management:reset
