Cloudflare Tunnel Error When Running shopify app dev - Persistent since 1 week

Hey everyone,

I’ve been consistently getting this error for almost a week now when trying to run shopify app dev on all of my apps (not just one):

Could not start Cloudflare tunnel: max retries reached.     

I’ve already tried:

  • Restarting the CLI and system several times

  • Testing on multiple apps (same issue)

  • Waiting it out. it’s been 6 days

  • --use-localhost (not viable since my app uses a proxy)

  • ngrok (also giving me unrelated issues)

So my main question is:
:backhand_index_pointing_right: Is Cloudflare tunneling currently down or blocked on Shopify’s side?
Or has something changed recently that we need to update in our environment/config?

Would appreciate any insight.

Hi @starliner

No changes on our side that I am aware of. Possible that something changed on your network and/or security policy? See the following docs from Cloudflare for information on required egress hosts and ports.

Hi there it turnt out my isp dns couldn’t be finding cloudflare anymore, eventually this prevented the app to launch. Very weird. Thanks for your insights.
