Setup: s3gw 0.23 rc2 via helm on longhorn in a k3s cluster. Connection through ssh tunnel through traefik ingres via https

Expected behavior:

Useful error message or a ui backend that fails to start on a precondition.

Probably due to incorrect backend url: │ INFO: 2023-11-21 14:24:29 -- config -- Servicing s3gw at https://s3gw-s3gw-s3gw.be.kubetest.foo

Would be good to check this on startup

@irq0 mind confirming whether you are running this though the helm chart, and which versions you set for the tags? If you did not adjust the ui's section imageTag to v0.23.0-rc, mind doing so, and test again?

[irq0]

Right, this was with v0.22. Can reproduce on │ Image: quay.io/s3gw/s3gw-ui:v0.23.0-rc3 │

The PR will partly fix the issue by displaying meaningful error messages that can be used to identify the root problem.

The follow up issue can be used to implement additional ideas.
