This document provides troubleshooting guidance for FQDN user login issues from third-party identity providers to fleet member clusters.

Client can't reach the authentication service

This issue occurs in one of the following cases:

  • You're using a version that doesn't support this user login method.
  • The control plane VIP doesn't route the traffic to the correct component.

Error message

  Error: could not start login. Please check if cluster supports server side authentication. Details: failed to ping well-known endpoint: Get "https://cluster-url:XXXXX/.well-known/configuration": dial tcp XXX:XXXXX: connect: connection refused

Solution

To resolve this issue, verify that you're using a version of 1.28 or higher and the version of the control plane that supports authentication using FQDN access.
