Hello Martin,
Thanks for the reply. The attached json output was the curl response from the okta and executed from vault itself.
I suspect that something was not configured in okta side. When I paste the URL to browser, I got the following error code
{“errorCode”:“E0000022”,“errorSummary”:“The endpoint does not support the provided HTTP method”,“errorLink”:“E0000022”,“errorId”:“oaeu-ftiv-DRuK45ElXHGzO7Q”,“errorCauses”:}
I tried some common OIDC Discovery URL and it does have a sign-in screen
