I’m trying to use Arctic with our on-prem S3 compatible storage.

I’m trying it with Dremio Cloud.

I’ve succeeded in creating an Arctic project and connecting it to an existing Sonar project following this guide: [https://docs.dremio.com/cloud/getting-started/arctic-set-up/](https://docs.dremio.com/cloud/getting-started/arctic-set-up/).

But when I tried the same method with our on-prem storage, I got the following error.

Failure creating/updating this source [Arctic-source-name].

In this trial, I set this Connection Property: {Name: fs.s3a.endpoint, Value: }.

Did I miss something?

For Arctic Preview we only officially support AWS S3 as a store. That said, we may be able to get this to work. Can you provide details on your S3 compatible storage setup? Are you using MinIO?
