Could you try again (with WinSCP)? R2 made a number of compatbility improvements in the last year and I'd be curious what issues its stiill having if any

AAzickri Hello, Cloudflare Team. I have a question about Cloudflare R2. I want to open a...

Its an error from Cloudflare telling you that it doesn't support the auth scheme that S3 Browser is trying to use. Does the application have an option to use V4 auth instead?

i tried recently and it doesn't work

ErisaOP•7/18/23, 11:59 AM

Any idea what error it gives? Or just generic?

PencilNavigator•7/18/23, 11:59 AM

"The request signature we calculated does not match the signature you provided. Check your secret access key and signing method."

ErisaOP•7/18/23, 11:59 AM

I see

ErisaOP•7/18/23, 11:59 AM

Thanks

PencilNavigator•7/18/23, 12:00 PM

i've regenrated 10+ times the credentals and no it doesn't fix the issue

PencilNavigator•7/18/23, 12:00 PM

every time when it reaches 5120KB it stops and pops this error

PencilNavigator•7/18/23, 12:01 PM

i am on the latest version of WinSCP

ErisaOP•7/18/23, 12:01 PM

Ah, probably something to do with multipart then

PencilNavigator•7/18/23, 12:01 PM

dunno

PencilNavigator•7/18/23, 12:02 PM

uploading to b2 works, s3 works, only r2 is not (with this error)

vassbence•7/18/23, 12:06 PM

Is there a speed difference between accessing the bucket via a public url and from a worker?

vassbence•7/18/23, 12:07 PM

Or rather, should there be a difference? I'm seeing lower latencies across the board when accessing files from inside a Worker

vassbence•7/18/23, 12:07 PM

What could be the reason behind it?

ErisaOP•7/18/23, 12:10 PM

Its expected that Workers will have lower latency but the difference shouldnt be too dramatic - what numbers are you seeing? And is it tested from the same regions?

vassbence•7/18/23, 12:13 PM

blue: worker
gray: public url

vassbence•7/18/23, 12:14 PM

it's not too dramatic tbh, i just wanted to know the fastest possible option

vassbence•7/18/23, 12:15 PM

i'm curious, why is it faster via a Worker? Doesnt the worker itself add like 30ms latency? Or with the worker the request gets on the cf backbone faster?

ErisaOP•7/18/23, 12:15 PM

Workers dont add 30ms latency to requests

ErisaOP•7/18/23, 12:16 PM

If I recall correctly I believe it was something to do with the binding not having as much auth overhead, like for S3 you have to sign the request and then verify the signature and all that stuff because the request goes through

ErisaOP•7/18/23, 12:17 PM

Public URL I'm not so sure on

vassbence•7/18/23, 12:17 PM

Seems like a valid explanation yeah..

How much overhead do workers add to a request? I mean it can't possibly be 0

vassbence•7/18/23, 12:18 PM

https://blog.cloudflare.com/cloudflare-workers-the-fast-serverless-platform/ this shows around 20ms TTFB in US regions

vassbence•7/18/23, 12:20 PM

Also, based on these outcomes should I just serve my files via Worker and not a public URL?

DaniFoldi•7/18/23, 12:20 PM

20ms sounds about right, the worker is loaded while TLS handshake & validation and everything is performed, so you don't really see the cold starts as much

vassbence•7/18/23, 12:23 PM

I just ran an artillery load test too, and files via workers is almost 2x.. guess i'll disable the public url and serve assets via workers

Vvassbence https://blog.cloudflare.com/cloudflare-workers-the-fast-serverless-platform/ thi...

ErisaOP•7/18/23, 12:26 PM

That 20ms would be for the whole request, not just the added latency from Workers

is s-maxages-maxage supported for R2 public urls? So will cloudflare honor the s-maxages-maxage set on the object?

vassbence•7/18/23, 1:07 PM

It does not seem like it

it does not get stripped and from that i'm assuming it's not getting cached

PencilNavigator•7/18/23, 1:38 PM

i think not, just like pages.dev (iirc)
just bind a custom domain

vassbence•7/18/23, 1:44 PM

Solution was that I needed to add the correct extension to the end of the filenames (was just using UUIDs) so that CF would cache them.

as per: https://developers.cloudflare.com/cache/concepts/default-cache-behavior/#default-cached-file-extensions

heartz•7/18/23, 1:59 PM

Hi, if I make an R2 bucket public, can the files in the R2 bucket be seen, or are files only available to clients if they know the file name?

ErisaOP•7/18/23, 2:01 PM

Theres no listing functionality for public, its only if they know the filename

Unsmart•7/18/23, 2:39 PM

(You still shouldnt put private files on a public url even if the file name is probably unguessable though

)

Soham•7/18/23, 3:06 PM

i mean you could if you enable access for it i guess

Unsmart•7/18/23, 3:13 PM

enabling access means it isnt a public url

KKarew What console errors are you getting?

Hi,

I'm wondering if I can use presigned url to do streaming upload ?

I tried to use the streaming upload:

     await axios({
                        method: 'put',
                        url: presignedUrl,
                        data: response,
                        headers: {
                            'Content-Type': 'binary/octet-stream',
                            'Transfer-Encoding': 'chunked'
                        }
                    });

     await axios({
                        method: 'put',
                        url: presignedUrl,
                        data: response,
                        headers: {
                            'Content-Type': 'binary/octet-stream',
                            'Transfer-Encoding': 'chunked'
                        }
                    });

it always returns http 411.
souds like it doesn't support ?

Not too long - whats the domain?

Original message was deleted

ErisaOP•7/18/23, 5:07 PM

I see a vague error on surveys.helpdesk.support.rydercragie.comsurveys.helpdesk.support.rydercragie.com

maybe its temporary? Could you try removing and readding the domain to nudge it again?

ErisaOP•7/18/23, 5:10 PM

Mine too somedays lol

ErisaOP•7/18/23, 5:11 PM

I think that's mainly forr the bucket connection which shows as Active. The problem is the certificate which requires kicking by redoing it

ErisaOP•7/18/23, 5:11 PM

If that still doesn't work I might have to try and find out what the error is trying to tell me, I've had no leads so far

ErisaOP•7/18/23, 5:14 PM

It shows in deleteddeleted state for me now, try adding it again

ErisaOP•7/18/23, 5:18 PM

lemme check
