📄 Website DNS Issues — What to Check

What This Covers

What to check when your Odoo website isn't loading or shows a DNS/connection error.

Steps

  1. Check if Odoo itself is up — Try accessing your Odoo backend (e.g., yourcompany.odoo.com/web/login). If the backend works but the website doesn't, it's likely a DNS issue.
  2. Check DNS propagation — Use a tool like dnschecker.org to verify your domain points to the correct IP/CNAME.
  3. Verify DNS records — Your domain should have a CNAME record pointing to your Odoo instance. Check with your domain registrar (GoDaddy, Namecheap, Cloudflare, etc.).
  4. SSL certificate — If you see a security warning, the SSL certificate may have expired. Odoo.com hosted instances handle SSL automatically, but custom domains need proper DNS configuration for SSL to provision.

Common Errors

  • Site shows "This site can't be reached" — DNS is not resolving. Check that CNAME records are correct and have had time to propagate (up to 48 hours for new changes).
  • Site loads without CSS/styling — Try clearing your browser cache or doing a hard refresh (Ctrl+Shift+R). If it persists, assets may need regenerating — submit a ticket.
  • "Slow site" after DNS change — New DNS records take time to propagate globally. Use dnschecker.org to monitor propagation progress.
