Configure JWT_Algorithms manually

To resolve the authentication failure, manually provide the list of supported algorithms in the platform gateway configuration.

Procedure

  1. From the navigation panel, select Access Management > Authentication Methods.
  2. Select your OIDC authenticator from the list.
  3. Click Edit authentication and locate the OIDC JWT Algorithm(s) field.
  4. Enter the list of supported algorithms as a YAML list or a JSON array. These algorithms are typically available from your IdP’s OpenID Connect (OIDC) discovery endpoint.

    Example

    [
        "PS384",
        "ES384",
        "RS384",
        "HS256",
        "HS512",
        "ES256",
        "RS256",
        "HS384",
        "ES512",
        "PS256",
        "PS512",
        "RS512"
    ]
  5. Save your changes. The system uses these specified algorithms for token verification, resolving any authentication failures related to their absence.
