Cloudflare Tunnel failed to request a quick tunnel

Retired Boards Appdev Tools

Topic summary

Developers are encountering failures when using Cloudflare Tunnel with Shopify CLI’s npm run dev command. The error indicates “failed to request quick tunnel” with connection issues from the remote host.

Workaround Solutions:

  • Switch to ngrok tunneling: npm run dev -- --reset --tunnel ngrok
  • Use custom ngrok tunnel: Run ngrok http 3000 in separate terminal, then shopify app dev --reset --tunnel-url https://{ngrok-url}:3000
  • Clear DNS cache: ipconfig /flushdns

Key Points:

  • Multiple users report the issue appearing intermittently over recent days
  • Cloudflare’s quick tunnels are described as unreliable (“flaky”) with no uptime guarantee
  • Shopify support recommends reporting persistent issues to the CLI’s GitHub repository
  • Some developers have permanently switched to paid ngrok subscriptions ($20/month) to avoid Cloudflare tunnel reliability problems

The discussion remains open as an ongoing issue affecting multiple developers, though workarounds are available.
