Hi again,

Got S3 to work. No idea what the issue was, but after a big headache here's what got it working:

Use Safari (instead of Arc), create a new account on Cloudflare with an email that isn't authenticated by google to sign in and boom! works.

Leaving it here in case it's helpful to anyone in the future. :) Thanks for the support.

Ahhh thanks! How much of a noblet Iam I'm with this.

It's been removed and the api was changed too just in case.

Sadly it didn't work too. :(

So after, I tried swapping the endpoint to "https://.fedramp.r2.cloudflarestorage.com" and the error message now switched to:

Hello,

Thank you for the quick response. Tried setting S3 the last couple of hours too without luck, using Cloudflare R2.

Followed this comment that someone kindly put in another thread:

"in simple steps:

1. go to the cloudflare dashboard
2. create a bucket
3. create an token to authenticate on the s3 api: https://developers.cloudflare.com/r2/api/s3/tokens/
4. go to siyuan configure the s3 sync with the information gathered on previous steps
5. after configuring the conection information go to cloud sync dir and add a directory for the sincronization"

following error when I try to sync:

Would you be able to point out what's wrong, or to where I should research more to get this sync'd please?

Thank you kindly
