I wanted to let you know that I've resolved the issue with the images not displaying. I removed the Custom Domains and switched to using the R2.dev URL. Now users can see the images without any problems.

Thank you all for your support and advice!

Probably because SNI isn't used on r2.dev @xlaber.

You should adjust your SSL for your zone instead, maybe order an advanced SSL cert

As Leo mentioned, you might not have much fun with this setup in production -> https://developers.cloudflare.com/r2/platform/limits/#rate-limiting-on-managed-public-buckets-through-r2dev

Cloudflare Docs

Limits | Cloudflare R2 docs

Managed public bucket access through an r2.dev subdomain is not intended for production usage and has a rate limit applied to it. If you exceed the rate limit, requests through your r2.dev subdomain will be temporarily throttled and you will receive a 429 Too Many Requests response. For production use cases, consider linking a custom domain to y...

STREAMING-AWS4-HMAC-SHA256-PAYLOAD not implemented Exception when upload
I'm using aws s3 android sdk to upload image to R2，the code is:
fun uploadBitmap(bitmap: Bitmap, fullPath: String){
val s3Client = buildS3Client(DEFAULT_CONFIG)
val outputStream = ByteArrayOutputStream()
bitmap.compress(Bitmap.CompressFormat.JPEG, 80, outputStream)
val byteArray = outputStream.toByteArray()
val metadata = ObjectMetadata()
metadata.contentType = "image/jpeg"
metadata.contentLength = byteArray.size.toLong()
val putObjectRequest = PutObjectRequest("posechallenge", fullPath, ByteArrayInputStream(byteArray), metadata)
try {
s3Client.putObject(putObjectRequest)
}catch (e: AmazonClientException){
Logger.error(TAG, e.stackTraceToString())
}catch (e: AmazonServiceException){
Logger.error(TAG, e.stackTraceToString())
}
}
finaly, I got a STREAMING-AWS4-HMAC-SHA256-PAYLOAD not implemented Exception,what's wrong?

Hi - Is it possible to increase the bucket limit from 1000 ?

birindar77•11/8/24, 9:52 AM

okay

I see what you mean with the ipv6 but it falls back on ipv4

XXander I see what you mean with the ipv6 but it falls back on ipv4

fry69•11/8/24, 11:52 AM

Falling back to IPv4 aka "Happy Eyeballs" is a browser thing, not a HTTP thing, fetch calls etc will not fall back to IPv4

Yes,but I can't disable it.In C#, it can be disabled by set DisablePayloadSign=true.

Hi there!
We are facing issues with end users uploading files to cloudflare R2. Our users upload files from their browsers using presigned urls. Sometimes they get 502 errors, usually when they upload 1000+ files in one go. Under the hood, not all uploads are started simultaneously . Usually there are 10-100 file uploads at the same time. I can't reproduce the errors, but they keep happening.
Are there any limits on R2 side that stop uploads or does anyone have an idea what could cause this error?
It's unlikely related to the underlying machine or internet connection since this is happening for multiple users of us.

fry69•11/8/24, 3:20 PM

Maybe this is naive but: 5xx errors are temporary and whatever uploads should then just try again (with exponential backoff at best)?

Original message was deleted

Carl•11/8/24, 3:28 PM

that might be the issue...
We implemented retries with exponential backoffs already

Carl•11/8/24, 4:00 PM

Alright, thanks for the help. I'll have a look on how I can reduce the concurrent load or spread the load otherwise.
I don't know if I didnt search enough, but I couldnt find this answer with google. Maybe you can add it somewhere in the docs for others who might face the same issue?

Carl•11/8/24, 4:01 PM

thank you

Carl•11/8/24, 4:04 PM

does this mean I can put roughly 200 4MB files at the same time?

Carl•11/8/24, 4:05 PM

and exceeding it might lead to 502 errors?

Carl•11/8/24, 4:05 PM

ah ok

Carl•11/8/24, 4:05 PM

thanks thats a number to work with

Carl•11/8/24, 4:10 PM

I think we're not using event notifications. But it's good to know. Are there other features on a default bucket setup that might impact this number?

Carl•11/8/24, 4:10 PM

alright, thanks for the help!

        {
            "code": 10001,
            "message": "We encountered an internal error. Please try again."

        }

I recently moved this domain from another of my cloudflare accounts to this account. Its been more than a day. I can attach subdomains of this domain to bucket but the root domain fails to be attached for some reason. How can i resolve this? Any tips?

turns out the old config from the previous account still persists. I thought once the domain moved it would remove any related config. But nope. You need to delete old bindings to R2 if you had any

hello people!~

I am trying to upload files to r2 using aws-sdk/client-s3 from workers.

question: do we need to cleanup file from worker memory once it's uploaded to r2?

context:
I had been using lambda heavily before I got into cloudflare stack and in AWS lambda, we would generally have a clean up mechanism incase there was an error or even in successfull execution, at the end to make sure the persistent storage doesn't get jammed; (eventhough its serverless, everything is stored in same allocated space for a period of 10 minutes or something)

thanks in advance!

shoo•11/8/24, 6:42 PM

incase the video got downloaded upto 90% and then failed - my worker will return a 500 error as well (according to my code) and that's it for this particular execution.

after this - will cloudflare take care of that 90% of the partially downloaded file and clear it from memory? let's say 50 Mbs
and I don't need to take care of that

shoo•11/8/24, 6:52 PM

but I was also talking about the persistent storage
I don't think js gc would be able to take care of the persistent storage
once its stored - its stored right

in serverless infra - they separate out all the resources and try to make it kinda independent from each other
but that won't be practical realistically - so this is what AWS does with lambda

and we have faced cases where this had become an issue before we implemented the cleanup

shoo•11/8/24, 6:52 PM

hence the question

Southpaw•11/8/24, 6:53 PM

They don’t have any persistent storage at all, I don’t think.

SSouthpaw They don’t have any persistent storage at all, I don’t think.

fry69•11/8/24, 6:55 PM

They don't even have a filesystem

shoo•11/8/24, 6:55 PM

Oh! I did not realize that
so it can't go over 128 MB for any case
and can only stored in memory

shoo•11/8/24, 6:56 PM

got the answer. thank you guys! appreciate it

DJ45X•11/8/24, 9:27 PM

looking to try using r2 as a solution to hosting the update files for an application i'm working on. i intend to use github actions to push the update files to the r2 bucket. for testing and familiarization, i tried using both rclone and awscli to simply browse the r2 bucket. awscli gives me the error "could not connect to the endpoint url: https://s3.auto.amazonaws.com" but i have specified my access key id, secret key, and r2 endpoint using the command aws configure setaws configure set. any thoughts or suggestions?

jogath•11/8/24, 11:25 PM

How do I see total R2 database usage over all time?

jogath•11/8/24, 11:27 PM

Is Average Storage "Amount of storage used for this bucket" what I am looking for?

An interesting way to use Cloudflare R2 in video players with different qualities and hover thumbnails (in the style of YouTube) is by using HLS. In this repository, I made a demo using only Cloudflare R2, and it works wonderfully! https://github.com/fernandodilland/r2-player.js Suggestions or improvements are welcome!

Hey guys

I'm new here. I was just wondering if there is a way to restore a R2 database (for example 2 days ago) ?

Anthony•11/9/24, 8:56 AM

R2 are using AWS S3 Buckets under the hood. There's no way to restore an S3 bucket?

Anthony•11/9/24, 8:59 AM

Got it, thanks

Anthony•11/9/24, 9:02 AM

Yeah I'll look at something

fry69•11/9/24, 9:02 AM

That said S3 seems to have some kind of versioning extension built-in -> https://docs.aws.amazon.com/AmazonS3/latest/userguide/Versioning.html

Use versioning in Amazon S3 to keep multiple variants of an object in the same bucket.
