O2O setup to Shopify fails for one specific edge (KUL, Malaysia) with simple passthrough worker
I got a bunch of 403 errors for all visitors from Malaysia since 11pm SGT 21-Oct. We are using cloudflare workers to modify some elements in our Shopify shop. To enable CF workers we proxy the traffic via our CF setup with a CNAME, also known as Orange-to-orange (O2O), .
We did not change anything about our setup and worker was smooth sailing ever since launched. Now the origin (Shopify) responds 403 for Malaysia only with a simple "You do not have permission to access this website".
Shopify support has done a reset "So we were able to do a Cloudflare refresh on your domain.". But once I enable the CF worker the issue returned after it did work fine for maybe a minute or 15.
I have done a purge all on our cache as well. A worker as simple as below already gives a problem, lol. But only for one node..
export default {
async fetch(request, env, ctx) {
return fetch(request);
},
};
