That error means the SSL certificate on your server is invalid (Cloudflare -> your server). The option above is for the Edge Certificate (visitor -> Cloudflare).
guys i just got billed for 9usd for usage of R2 bucket for the past month even if i was well below the thresholds for class A and B operations and the data storage was just for 20gbs only, the invoice is still not available to see though, is this an error in your opinion? will they refund me?
i had some videos that got passed into the infrequent access category because i had set it to do that after 30 days, i have now removed this setting, the infrequent access constitutes only 300mbs of the full bucket size of 20gbs from what i see
IPs just get you to Cloudflare, every server within Cloudflare handles your request. You could connect with a random IP found on Google and your site would still be served
What happens at Cloudflare and more likely the cause, your origin is unrelated.
Yeah, that would do it. Infrequent Access is almost always more expensive than Standard. Unless you have a huge R2 bill, you don't even need to consider IA. And even if then it's unlikely to save you much, if it all.
