401 Unauthorized error using the Rancher2 Terraform Provider v1.4.0 with `access_key` and `secret_key` authentication

This document (000020065) is provided subject to the disclaimer at the end of this document.



Executing Terraform actions against Rancher v2.x, with the Rancher2 Terraform Provider v1.4.0, results in an error of the following format, when using access_key and secret_key authentication:

Error: Bad response statusCode [401]. Status [401 Unauthorized]. Body: [message=must authenticate] from [https://xyz.rancher.com/v3]


  • A Rancher v2.x instance
  • The Rancher2 Terraform Provider v1.4.0
  • Rancher2 Provider authentication with separate access_key and secret_key


To workaround the issue use token_key authentication.


The issue was fixed in Rancher2 Terraform Provider v1.4.1, so you should upgrade to a later version of the provider.
