Details about 510-401 Unauthorized

This error code includes cases like

  • The header was missing
  • The token could not be decoded
  • The token is from a different realm than the tenant in the request path
  • The token was expired (exp), not yet valid (nbf) or issued in the future (iat)
  • The token's issuer (iss) did not match the expected value discovered from the IdP
    • This is most likely a realm configuration problem in Keycloak, such as not configuring the "Frontend URL" setting in the realm, which is required in a typical setup
      • Failing to configure the Frontend URL will result in a mismatch between the issuer URL that was discovered by the service inside the cluster, and the issuer in the JWT issued for a client outside the cluster
    • After changing the realm configuration, it is necessary to restart the service in order for it to rediscover the realm configuration
  • The token's audience (aud) didn't include all required values specified in the service config (default: none)
  • The token's signature did not match the public key discovered from the IdP
