I see what you mean with the ipv6 but it falls back on ipv4
I see what you mean with the ipv6 but it falls back on ipv4
FFalling back to IPv4 aka "Happy Eyeballs" is a browser thing, not a HTTP thing, fetch calls etc will not fall back to IPv4
AYes,but I can't disable it.In C#, it can be disabled by set DisablePayloadSign=true.
ANow I'm work with postman to test R2 API,When I pass the Header 'Date' with 'Fri, 08 11 2024 12:42:51 GMT' or 'Fri, 08 Nov 2024 20:42:51 GMT', the server retrun
Date provided in 'date' header (Fri, 08 11 2024 12:38:00 GMT) didn't parse successfully
So, What's the right Date format?

CHi 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.

FMaybe this is naive but: 5xx errors are temporary and whatever uploads should then just try again (with exponential backoff at best)?
Cthat might be the issue...
We implemented retries with exponential backoffs already

CAlright, 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?

Cthank you
Cdoes this mean I can put roughly 200 4MB files at the same time?
Cand exceeding it might lead to 502 errors?
Cah ok
Cthanks thats a number to work with
CI 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?
Calright, thanks for the help!
Phey, i am trying to set a custom domain to my bucket and i get error:
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?

Pturns 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
Shello 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!

Sincase 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

Sbut 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

Shence the question
SThey don’t have any persistent storage at all, I don’t think.
FThey don't even have a filesystem
SOh! I did not realize that
so it can't go over 128 MB for any case
and can only stored in memory

Sgot the answer. thank you guys! appreciate it
Dlooking 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 set. any thoughts or suggestions?
JHow do I see total R2 database usage over all time?
JIs Average Storage "Amount of storage used for this bucket" what I am looking for?
FAn 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!

1Very cool! Will definitely take a look, I might have a good use case for this
AHey guys 
I'm new here. I was just wondering if there is a way to restore a R2 database (for example 2 days ago) ?

AR2 are using AWS S3 Buckets under the hood. There's no way to restore an S3 bucket?
AGot it, thanks
AYeah I'll look at something
FThat 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.
FIt should be possible to create similar versioning with R2 and the tools available, just not an out-of-the-box service
FI learned how to publish the library on NPM. In case it’s helpful, here’s the link: https://www.npmjs.com/package/r2-player.js

IDoes R2 offer signed url?
FCloudflare Docs
Presigned URLs are an S3 concept 
for sharing direct access to your bucket without revealing your token secret. A presigned URL authorizes anyone with the URL to perform an action to the S3 compatibility endpoint for an R2 bucket. By default, the S3 endpoint requires an AUTHORIZATION header signed by your token. Every presigned URL has S3 param...

NI created a bucket, but i don't see tab Access Keys
Nhelp me, please
N
Ncreate API token ?
N
NIs this correct, sir?
Nthank you so much, i'm done
NI got this error when I sent a link to my friend to see photos on r2
Nhow to use, thanks for helping me
ĐCould you confirm if this is bug? If I use the endpoint create by API, it will create
content-disposition properly. But if I use custom domain endpoint, it only delivery the file, the http header will not be generated like in the screenshot. If it is not a bug, could you tell me how to inject content-disposition in the right way?
ĐThanks, but do we have other options to set filename for download link using custom domain?
ĐAlso where can I read more about this?
