  • Must be unique - Not already in use by another project
  • Reserved names: www, api, admin, mail, ftp, localhost, test, staging, dev, app

​
Troubleshooting

​
Domain Verification Fails

  • Check DNS propagation: Use dig yourdomain.com or online tools
  • Wait for propagation: DNS changes can take up to 48 hours
  • Verify record type: Ensure CNAME or A record is correct
  • Check domain format: No typos in domain name

​
SSL Certificate Issues

  • DNS not propagated: Wait longer for DNS
  • Invalid DNS configuration: Verify records point correctly
  • Domain already in use: Check if used by another project

​
Domain Not Working

  • Check deployment status: Ensure project is published
  • Verify SSL certificate: Check certificate status in Publish Modal
  • Clear browser cache: Try incognito mode
  • DNS propagation: May need more time
