I’ve followed all tutorials I could find on how to proxy Backblaze bucket through Cloudflare but I keep getting infinite redirects. I tried it both using page rules to exclude all buckets not belonging to you, and vanilla without any rules.
In my case my image subdomain points CNAME to f002. backblazeb2.com with cloudflare proxying on.
It caches the redirect response though
I don’t know if this is an issue on CloudFlare or BackBlaze (the file is viable OK using the normal f002. backblazeb2.com domain)
