Minio / S3 backup configuration no longer working (region is wrong error)

xarp

Description

Minio has been working flawlessly for years as the configured backup destination. Ever since the automatic Cloudron update to 9, the Minio/S3 backup fails due to a region configuration issue.

I could have sworn the previous Cloudron versions had a "region" option in the S3 configuration. However, now there is none. And would probably explain this resulting issue.

Possibly related to this recent issue: https://forum.cloudron.io/topic/13970/error-configuring-backup-cloudflare-r2-object-storage

Steps to reproduce

Configure Minio backup with a region configured, and attempt to add it. Alternatively, test your existing Minio implementation w/ configured region, and attempt to run a backup.

Troubleshooting Already Performed

Removed and attempted to re-add Minio backup configuration, but it errors out with the same thing and doesn't allow me to save it now.

Cloudron Version

9.0.13

Ubuntu Version

Ubuntu 24.04

Minio is basically dead for community edition.

I rolled back to image: quay.io/minio/minio:RELEASE.2025-04-22T22-12-26Z (last version with all management features - don't expose it publicly for security reasons)

Then: Configuration > Region > Restore Defaults

That wiped my region entry and now Cloudron connects properly again. Time to consider successor software now.

I have had a similar problem - a minio install which had been my Cloudron backup destination for years suddenly giving me a region error and not working. I just installed raw minio, which did not include a region setting, and now it works.

EDIT: I often neglect to keep track of the intructions I used to install this or that, but in this case I saved it. I followed the instructions here for Minio - https://www.atlantic.net/dedicated-server-hosting/how-to-deploy-minio-on-ubuntu-24-04-an-open-source-object-storage-application/
