Recommendations

  • Unable to determine hostname. API request may have failed.
  • Your site is not using HTTPS. Configure SSL for better security.
  • NEXT_PUBLIC_SITE_URL environment variable is not set. Set this to your custom domain.
  • VERCEL_URL is not available. This is normal in local development but should be available in Vercel deployments.
For DNS issues, ensure your domain has an A record pointing to 76.76.21.21 or a CNAME record pointing to cname.vercel-dns.com

Environment Variables Guide
Understanding important environment variables for domain configuration

VERCEL_URL

This is automatically set by Vercel in deployments. It contains the URL of your deployment (e.g., project-name-git-branch-username.vercel.app). It's not available during local development.

NEXT_PUBLIC_SITE_URL

This should be manually set to your custom domain (e.g., https://yourdomain.com). It's used by your application for generating absolute URLs.

Setting Environment Variables

You can set environment variables in your Vercel project settings:

  1. Go to your Vercel dashboard
  2. Select your project
  3. Click on "Settings" tab
  4. Navigate to "Environment Variables"
  5. Add your variables (e.g., NEXT_PUBLIC_SITE_URL)
  6. Redeploy your application
