Free License Key Request Fails with 403 Error on Self-Hosted VPS (Hostinger)

Hi n8n Team,
I’m running n8n self-hosted on Hostinger VPS (Ubuntu 24.04, Docker Compose template).
When I try to request the free license key for advanced features, I get this error:
“License request failed
Failed to register community edition: connect ETIMEDOUT 172.67.68.102:443”
Steps I tried:

  • Used different emails (e.g., [email protected])
  • Checked spam/promotions folder
  • Tested network: curl -I https://license.n8n.io returns HTTP/2 404 (connection OK)
  • Tunnel mode (N8N_TUNNEL=true) also failed with 403
    n8n version: [你的版本,SSH 中 docker compose logs n8n | head -1 查]
    VPS IP: 72.61.112.205
    Domain: n8n.srv1093996.hstgr.cloud
    Any help or workaround? Thanks!
    Best,
    Silvia
