App Proxy not forwarding requests – Outage? Production service, no changes

Hydrogen and Storefront APIs

About an hour ago a significant portion of our app proxy requests stopped forwarding to our production server.

Tailing the logs, I can see that some requests are forwarded, but the majority are not, suggesting a partial outage of an internal service. Nothing has changed in our app config, and the developer panel shows perfect API health so it’s not a result of deprecated API requests.

You can view my app’s demo store for an example of this: Members-Only: Guitar (Free Shipping) – MagicPass

This page makes a request to https://password-protected-pages.myshopify.com/apps/password-protect/uninstalled which should return a 200 OK. Instead the request is dropped before hitting my server, returning a 404.

I checked the Shopify changelog for references (no breaking updates to the app proxy AFAICT). The shopify status page is green. I’ve also deployed a new app version using shopify app deploy in case it would trigger an internal reset. That hasn’t helped.

Are any other developers experiencing this?

I believe this was a partial outage. It’s working again, with no changes on our end. I hope Shopify’s internal monitoring can catch this a bit faster in the future.

Hi @Impress, this was a temporary outage on our end and has since been resolved.

Hi @Darpan_Rajput, thanks for reporting this.

We experienced a temporary CORS issue that affected app proxies, and we’ve deployed a fix that should resolve it. Can you confirm if you’re still experiencing issues?
