Free License Key Email Not Arriving (Self-Hosted Docker 1.122.5)

Hello Community,
I am running a self-hosted n8n installation using the Docker image n8nio/n8n:1.122.5.
I am trying to get the free license key to activate the paid features (Advanced debugging, Execution search and tagging, Folders), as shown in the attached screenshot.
I entered my email and clicked “Send me a free license key,” but the email never arrives.
I have checked my spam/junk folder.
It has been over 1 hour.
Could this be a connectivity issue between my Docker container and the n8n license server? Is there any specific log or environment variable I should check?
Thanks for your help!
