EHi! Have u any tutorial how to serve video and photos from R2?
秋Error during file upload: STREAMING-AWS4-HMAC-SHA256-PAYLOAD-TRAILER not implemented
I use R2 for .NET Core project, How do I fix it?

GHi, I'm getting a 403 when trying to upload via a presigned url when the Content Disposition is present. Here is the code: https://v0.dev/chat/next-js-file-upload-to-r2-IoXp2ML95m0?b=b_HDpfC8qyYdG
create a nextjs application for uploading file into cloudflare r2 using presigned urls
Ahi guys!
does R2 ban account if is used for P2P chat app to serve media files like mp4 / jpeg ?
does this violate R2 TOS ?
thank you!

Adoes Cloudflare offers custom plan if extra bandwidth is needed?
Ai mean to load faster, not to create extra storage
Athis one -> Egress (data transfer to Internet)
AI see.. thank you very much for your answers! Have a great day!
VI'm only using R2 and wanted to open a support ticket by upgrading to a pro account. Though, as I understand I can upgrade it only if I have a domain registered on Cloudflare. Is there a way to upgrade my account only while using the R2?
Vabout the errors I got while uploading chunks with multipart uploads
Vhow can I create? I see the suggestion of joining discord server when I try opening an issue via https://dash.cloudflare.com/?to=/:account/support or upgrading to business account to start a chat. I don't want to ask through chat though as https://developers.cloudflare.com/support/contacting-cloudflare-support/#live-chat-support states that it is for non-technical asks.

Varound 100$, but I'm ok to pay monthly fee for pro account
Vthe one I've asked you before, getting 5xx while uploading chunks with multipart upload. You've suggested retrying it and it kind of solved the problem (not 100% though). I'm planning to bet heavily on R2 but want to understand why I'm getting unrelated errors.
VI looked through the r2 doc but couldn't find related limits, are those limits documented anywhere
VI think it is not about advertisement but more about setting expectations
Vyes, but with crazy egress fees on s3
VI'm getting 5xx for buckets which I don't send more than 300 put rps. But in total, for all the buckets I have, I can send more than 300 requests
Vthen I'm hitting another issue or another limit
Vvia which url are you getting this page, this one https://dash.cloudflare.com/?to=/:account/support ?
VI don't understand what you mean. I'm creating buckets and token per bucket to access
Vyes, I'm. I've 10s of different hosts on hetzner and virtual machines are running on them. Then, I'm accessing R2 via those vms.
THey Cloudflare wizards! 
I’m serving small files (cached) and 250GB monsters (uncached) via R2/B2 + Cloudflare. I want to use free egress wisely and avoid ToS landmines.
Your battle-tested advice needed:
Cache Behavior:
If I set a 1-year TTL for small files, does Cloudflare actually keep them cached, or do they vanish early (LRU)?
Do rarely accessed 5GB files get purged faster than popular ones, even with valid TTL?
Giant Files & Range Requests:
When users stream chunks of a 250GB file (via Range headers), does Cloudflare:
Cache the entire file (even if only a small range is fetched)?
Risk ToS issues if many users stream different ranges of the same uncached file?
If I split a 250GB file into 5GB chunks, will Cloudflare cache those and handle range reassembly? (Or is this chaos?
)
Bandwidth Hacks:
Can I use R2 for hot files (cached) + B2 for cold files (direct) to minimize egress and stay compliant?
Any Worker magic to “force” cache retention for critical files without angering the Cloudflare gods?
Metrics to Watch:
What dashboard stats scream “You’re about to hit a ToS limit!”?
Goal: Serve users reliably (even with range requests!) without waking up to a blocked account.

Tyou cannot mix r2+b2 if you serve media files
what do you mean by that?
to 50MB chunks and then let clients fetch the ones that are needed
this will yield better performance and cache ability
-----
i thought if can use range requests for downloading it would be the same as saving as chunks.
if i use proxy worker to download ranges from B2 and cache them by key file_namefrom{}to{} ? would it be the same ?
if you need 250GB files regularly I would highly recommend staying away from uploading it using multiparts, best results i could get is with queue worker, i got to 1 GiB per minute transfer rate from B2 to R2 using multipart upload.

PHey all, I'm using aws s3-client to upload batches of files to R2 and I'm intermittently getting . I'm not doing anything out of the ordinary outside of PutObject commands here. Anyone experience similar and have any tips to stop this? I was previously using the same code to do this straight to S3 and never had a socket hang up or any other issue.
Pi don't know that timeouts are being handled within the s3 client's auto retry handler
Pthe default is 3 attempts
P¯\_(ツ)_/¯ okeedokee. happy to try anything 
Pi don't see http options for timeouts
P(within the s3client)
P@aws-sdk/client-s3
PS3Client
Pyes
Poh jeez they made it a big pain with multiple dependency options https://github.com/aws/aws-sdk-js-v3/blob/main/UPGRADING.md
PrequestTimeout numberThe number of milliseconds a request can take before automatically being terminated. Defaults to 0, which disables the timeout.
the default is that timeouts are disabled
DHello everyone, I would like to ask if accessing Cloudflare R2 in China will result in 610 or 611 responses. How can I use the CDN service normally in China? How to enable the China Network?
DWe consulted with Cloudflare Enterprise, and the cost is at least $5000 per month. However, our current usage does not meet this requirement. Can the Argo Smart Routing service be accessed in China? Is it possible to configure it via Workers, such that networks outside of China use Cloudflare CDN, while networks inside China use another network to download resources from R2?
DWe have an app store, and Android devices worldwide (including China) download APKs from the app store. Previously, we hosted the APKs on AWS S3, but the traffic costs were very high. We plan to migrate to Cloudflare R2 to reduce costs.
ECloudflare provides no latency, performance or availability guarentees for accessing their service from inside China unless the China Network is purchased and setup (which yes, is very expensive).
So while R2 may work and you're welcome to use it if it does, the files will be stored and served from outside China and if there are performance or availability issues affecting China users then Cloudflare may not be able (or willing) to do anything about it. Very much an "at your own risk" thing.

D80% of our Android devices are outside of China and 20% of our devices are in China
SHello, can I ask a question here?
