Saml-Session Cookie

I am running your Example Idp ASP.Net using ComponentSpace v4.2.0. My SP is in .Net 4.7.2.
I checked my browser cookie and did not find SAML_SessionId cookie. What could i be missing?The sp is able to send login and logout request to idp and also receive response but the idp can’t send logout requestCould the missing cookie be the reason ?All functionalities where working before upgrade

That could be the case. The cookie is marked as Secure and SameSite=None. Please ensure you’re using HTTPS. For information on the SameSite setting, please refer to:

If there’s still an issue, please enable SAML trace and send the generated log file as an email attachment to mentioning your forum post.

Also capture the SSO and SLO network traffic using the browser developer tools (F12) and send the HAR file.
