Hello Everyone,
I am setting up a new public app (in dev right now, installed on a development store) with an app proxy to an external API I host. It was working yesterday, and we had an issue and had to spin up new instances on our load balancers. Now it appears Shopify directly returns a 401 to the app proxy regardless of the code on the server. We have repointed it and it just 401’s regardless. The 401 is not from our end.
Is there some sort of method internally that could cause this? I’ve tried reinstalling the app. I’ve tried changing all of the parts of the proxy.
This isn’t my first app proxy either, its validating the HMAC etc all fine on our side when it gets the request. I even checked the access logs and there isn’t any sign of these hitting the server. The URL itself works in postman etc.
Can anyone help me out here? Its driving me nuts. Might just try making an entirely new app but that seems unnecessary.
