Original GitHub issue: https://github.com/eduardolat/pgbackweb/issues/117

It seems that it's not possible to use the R2 Object Store as the S3 destination.

Cloudflare R2 does not have the region concept, and on pgbackweb S3 configuration, it shows the Region as required. I tried to don't fill it and Test the connection, but did not work.

Also at Cloudflare panel, when I create the access to R2 bucket, I received an API Token, I'm not sure if its required or not.

I use the R2 Object Store with success to backup Portainer config.

@possebon According to the docs:

When using the S3 API, the region for an R2 bucket is auto. For compatibility with tools that do not allow you to specify a region, an empty value and us-east-1 will alias to the auto region.

Try setting to "auto"

Worked perfectly! Thanks. To work it's required to put the https on the endpoint also.
