Hello,
I just set up a new self-hosted n8n instance and tried to activate
the free license key, but I’m getting the error “Activation key has
already been used on this instance.”
This is a fresh installation on:
Could you please help me get a new activation key or reset the
current one?
Thank you!

try running this command on the CLI or your terminal
n8n license:clear
it will Clear your existing license from n8n’s database and reset n8n to default features
and try to activate the key again
if that still does not work then i suggest for you to contact [email protected]
hope it helps!
Can you trying running n8n license:clear and then restart n8n and see if you can then apply the license?
