Hey @ganhecomigoba Welcome to the n8n community!
Can you try changing your email and request again to activate your n8n, This is an issue which has happened before with users and i think it’s going to be fixed soon.
Or there one more thing that you could try as to run this curl maunally via command line and register this way.
Here is code for your help :
curl 'https://enterprise.n8n.io/community-registered ’
-X POST
-H ‘content-type: application/json’
–data-raw ‘{
“email”: “your@email.com”,
“instanceId”: “your-instance-id”,
“instanceUrl”: “http://your-instance-url”,
“licenseType”: “community-registered”
}’
I cURL above may or may not work but it is worth a try but i think it probably should, and if you still have problems you can reach out to license@n8n.io.
You can reference this post as this worked for this user : License key request always returns 403 error
