When use CDN, google merchant center can’t crawl all links, it shows http 4xx error.
1, Use Cloudflare CDN, google merchant can’t crawl url and get http 4XX error.
2, Turn of cloudflare CDN, and only use DNS, everything became to well, no error.
3, I have ever used Akamai CDN, never met any error, including this error.
4, Google service can’t give out the exact error code, i don’t know it is 403 or 404.
I submitted a ticket 1837392, but nobody want to solve this matter, only thought the matter is caused by my server, that’s a joke. And reply any information after 24 hours, i don’t know if cloudflare can solve this matter within one year according to the customer service efficiency, so i have to ask for help through community.
