## TL;DR

Working S3-backend config for non-AWS (OCI) object storage on Terraform 1.7.4+: use the endpoints block and the skip flags, with the default credentials file and no env vars: backend "s3" { bucket = "..." key [your value] region = "eu-frankfurt-1" endpoints = { s3 = "https://YOUR-NAMESPACE.compat.objectstorage.eu-frankfurt-1.oraclecloud.com" } skip\_credentials\_validation = true skip\_metadata\_api\_check = true skip\_region\_validation = true skip\_requesting\_account\_id = true skip\_s3\_checksum = true use\_path\_style = true } Thread: https://github.com/hashicorp/terraform/issues/34053

## Steps

1. Working S3-backend config for non-AWS (OCI) object storage on Terraform 1.7.4+: use the `endpoints` block and the skip flags, with the default credentials file and no env vars: `backend "s3" { bucket = "..." key [your value] region = "eu-frankfurt-1" endpoints = { s3 = "https://YOUR-NAMESPACE.compat.objectstorage.eu-frankfurt-1.oraclecloud.com" } skip_credentials_validation = true skip_metadata_api_check = true skip_region_validation = true skip_requesting_account_id = true skip_s3_checksum = true use_path_style = true }`

## When to use

You are seeing this: Terraform - ### Terraform Version ``shell Terraform v1.6.1 on linux\_amd64 + provider registry.terraform.io/hashicorp/null v3.2.1 + provider registry.terraform.io/hashicorp/oci v5.9.0 + provider registry.terraform.io/oracle/oci v5.1.0 `` Use this skill when you run into "S3 backend on nonAWS implementation (OCI) not working in 1.6.3".

## When not to use

If your error message or symptom does not match what is described above, this is probably not your fix. Search for your exact error text instead of forcing this one to fit.

## Versions

Versions mentioned in the source: Terraform v1.6.1, v3.2.1, v5.9.0, v5.1.0, v1.5, Terraform 1.7.4. If you are on something much newer or older, the details may have shifted.

## Why this happens

The original report does not dig into a root cause. It documents the symptom and the fix that resolved it.
