Aspire Dashboard - Using self signed certificate with OIDC

[iateya]

I am deploying an Aspire Dashboard pod on K3s (container image v13.1.0). I want to use OIDC for authentication. I have a keycloak pod running on the same cluster and it is using a self signed certificate. I set this environment variable in Aspire Dashboard pod.

AUTHENTICATION__SCHEMES__OPENIDCONNECT__REQUIREHTTPSMETADATA: "false"

But I am still getting this error

      System.InvalidOperationException: IDX20803: Unable to obtain configuration from: 'KEYCLOAK_URL_OMITTED'. Will retry at '2/23/2026 11:11:11 AM +00:00'. Exception: 'System.IO.IOException: IDX20804: Unable to retrieve document from: '[PII of type 'System.String' is hidden. For more details, see https://aka.ms/IdentityModel/PII.]'.        ---> System.Net.Http.HttpRequestException: The SSL connection could not be established, see inner exception.        ---> System.Security.Authentication.AuthenticationException: The remote certificate is invalid because of errors in the certificate chain: UntrustedRoot

How can I skip the SSL verification?
