S3 Help

[mynameiskali]

I'm like 90% sure I have configured my bucket (S3-compatible from Backblaze with a Fastly CDN) correctly, but whenever I try to use it I get "All files failed to upload"

S3 Endpoint: https://s3.us-west-004.backblazeb2.com
Region: I have tried a number of options, including us-west, us-west-004, us-west-004, and just leaving it blank
Access Key ID: 004xxxxxxxxxxxxxxxxxxxxx7
Secret Access Key: xxxx
Bucket: kalis-files
Public URL: https://cdn.dystopia.zip

The public URL is set up as a Fastly CDN with TLS, that should be set up correctly (even if it's wrong I don't see how it would effect uploading).

Any ideas? Have I missed something obvious? Thanks in advance- I know this probably isn't a typical thing you get asked as a Discord plugin dev lol.

im also interested in using backblaze b2 for storage with this plugin. did you ever get it figured out? what is a CDN?

Check in the console if you get any errors, sometimes they can only be seen in the Networks tab.

request headers aren't accepted with cors by default

λ cat rules.json

    "corsRuleName": "s3FromAnyOrigin",

@fijibestwater a CDN refers to a software that downloads something and then re-uploads it
i.e. discord uploads to backblaze, backblaze uploads to the CDN, then when you send the link to someone it uses the custom URL from the CDN which is good as it allows a custom URL and its faster than backblaze usually. sometimes CDNs also allow for other stuff like DDoS protection or extra statistics.

@yellowsink i had thought i had fixed my CORS settings, but maybe i hadnt, thanks. ill try again now.

[mynameiskali]

@xirreal i've set CORS to allow sharing with any origin & tested this again, i'm still getting the same ambiguous error with nothing in the network logs.

[yellowsink]

did you set cors via the web UI or via the command line as I showed? the web UI is not sufficient due to additional headers sent by the client.

[mynameiskali]

ah no i did it by the UI, thanks for pointing that out
