You can cache files with the CDN

Hi. The videos in my r2 bucket cannot be played by mobile. This error has just occurred, what is the reason? No error log appears.
Example:https://cdn.anizium.com/Anizium%2FAnimeler2%2Fcharlotte/charlotte-1-1-2160-jp.mp4

DreamSoldier•10/24/23, 5:28 PM

And of course, there are freezes when watched on a computer. They said something about Turkey ban. Could this be the reason?

Unsmart•10/24/23, 5:36 PM

Cloudflare doesnt not ban any countries sometimes governments will block some cloudflare IPs but afaik theres not any issues in Turkey right now and it would be very noticeable if it was.

I assume both those issues are just due to the video being so large and as a single mp4 instead of many parts

Unsmart•10/24/23, 5:37 PM

It works fine for me on PC but probably because I have 2gig internet. Cloudflare stream would probably be good for you or try to create many quality options with some service before uploading to R2

DreamSoldier•10/24/23, 5:38 PM

But until 2 days ago, it was opening without any problems on all devices. First, the pub url gave an SSL error for no reason. When I switched to the cdn.anizium.com url, it would run smoothly for 1 day, and then this problem occurred.

DreamSoldier•10/24/23, 5:41 PM

Now the pub URL opens on every device. Only cdn.anizium.com url does not work on mobile devices. I authorized all of them in Cors.

Hi all, I'm trying to determine if R2 is appropriate for my use case. I just want to serve a single, static .epub and be able to track download metrics. Is R2 a good solution for this? If so, what can I expect for billing/bandwidth charges, especially if there are abnormal spikes in bandwidth; and what do I need to do in order to track the number of downloads? Currently testing on a dev bucket.

Z•10/24/23, 6:02 PM

Awesome -- it says for a dev domain "usage is rate-limited and is not recommended for production"; do I just need to set up a custom domain? And will that give me more extensive logs/metrics than what is available on the dev bucket?

Z•10/24/23, 6:04 PM

Ok great, thanks

Z•10/24/23, 7:55 PM

Oh one other question - what is the rate limit on an r2.dev bucket?

Erisa•10/24/23, 8:37 PM

Its not documented. Ideally you shouldnt worry about it and should just not use r2.dev for anything except development and testing (for which you wouldnt need to know the exact limits)

Karew•10/24/23, 8:42 PM

You can create an R2 token that only has read/write access to specific buckets

Z•10/24/23, 9:13 PM

Can I have my root domain DNS resolve to vercel, with a subdomain DNS resolving to the R2 bucket?

Z•10/24/23, 9:13 PM

The domain is regestered through Cloudflare

Erisa•10/24/23, 9:35 PM

Yes you can

hanpolo•10/25/23, 1:29 AM

Sorry for the very basic question here. If I do a

const data = await MY_R2_BUCKET.get(key);

const data = await MY_R2_BUCKET.get(key);

can I just go

const mytext = await data.text()

const mytext = await data.text()

to get the data as text?

kian•10/25/23, 1:30 AM

Yes

hanpolo•10/25/23, 1:31 AM

Thanks much

Sam•10/25/23, 7:39 AM

I personally doubt it, but you could create the same effect using KV (or D1) and Workers (and Workers cron triggers, to run a daily check)

Should also keep in mind any local browser and/or cdn caching

sathoro•10/25/23, 7:44 AM

sathoro•10/25/23, 7:48 AM

it's incredible

kian•10/25/23, 7:49 AM

I can see how there'd be a few considerations - i.e if you add a LastAccessedLastAccessed time to objects then are there any clients which will throw due to an unexpected key in the schema? But, like most R2 extensions to S3, they could just throw it in a custom header (or re-use Last-ModifiedLast-Modified).

kian•10/25/23, 7:49 AM

It'd be cool to have

KKarew You can create an R2 token that only has read/write access to specific buckets

Айрат Х.•10/25/23, 8:14 AM

I created a token, but I don’t see in the documentation how to make an API request to download a file
I only found this https://developers.cloudflare.com/api/operations/r2-list-buckets

Cloudflare API Documentation

Does Super Slurper have a public API to initiate migrations programmatically?

If there is a better place to ask this Q, let me know

kev-ac•10/25/23, 7:00 PM

I've added a new zone and a custom domain on a R2 bucket during the "outage" today as these API endpoints seemed to be fine. My problem is that the connection of the bucket to the zone failed and now I'm unable to do anything. No matter if I click "Retry connection" or "Remove domain" I get a The specified bucket does not exist. (Code: 10006)The specified bucket does not exist. (Code: 10006) error. I can create another custom domain on the bucket and it works fine.

kev-ac•10/25/23, 7:01 PM

Is there someone from CF I can give my account ID and bucket name to to have a quick look at it?

kev-ac•10/25/23, 7:54 PM

I don't think there is an official API endpoint for super slurper, just for sippy.

Bruce Liu•10/26/23, 7:32 AM

I am using cloudflare R2 to upload a video and then play the video, and there are many problems that are difficult for me to understand. Can anyone help me? This is a picture that may appear. When I click on the video progress bar, it turns out that A 200 status code appeared, and then it started trying to download the entire video, OMG!!! I was using a domain I hosted on cloudflare. When I paused the domain on my cloudflare, it went back to normal. .Can anyone help me?

Bruce Liu•10/26/23, 7:46 AM

Has anyone encountered this kind of problem? It’s really difficult.

Erisa•10/26/23, 8:29 AM

What method are you serving the R2 bucket through? A Worker or a custom domain?

EErisa What method are you serving the R2 bucket through? A Worker or a custom domain?

Bruce Liu•10/26/23, 9:21 AM

I usea a Custom Domain.
When I used the Public R2.dev Bucket URL, this problem did not occur.

Bruce Liu•10/26/23, 9:24 AM

Of course, if the developer mode is turned on, this problem will not occur. I am really confused. I have turned off all the cloudflare options under my domain name. But it still doesn’t work. I can only choose developer mode, this situation will not occur.

Looks like its the known issue with files that are too large to fit into cache, the workaround is to bypass cache for these files using Cache Rules

Bruce Liu•10/26/23, 9:48 AM

OK, the video file is 5GB in size. However, I'm going to try writing rules now, bypass caching, and try.

Bruce Liu•10/26/23, 9:59 AM

I bypassed all caches through PAGE RULES, but unfortunately, it didn't take effect~

Bruce Liu•10/26/23, 10:04 AM

The cache rules are set like this, I don’t know if it takes effect. But the problem still exists, and the request status code of 200 still appears.

Karew•10/26/23, 10:22 AM

Did you clear your existing cache? Also you can try the new Trace tool to check if rules are being applied to a request https://blog.cloudflare.com/traffic-transparency-unleashing-cloudflare-trace/

Bruce Liu•10/26/23, 10:47 AM

https://kangeshu.xyz/loki.mp4 This is my video link. When I slide the progress bar, I can still see the 200 request status code. I am going crazy.

Hello, I’m Allie!•10/26/23, 11:27 AM

Given that I upload a PNG to this Worker, is there any reason why it would return corrupted?
