Hi,

Our application is running on Pega 7.3 version. We are using SSO authentication for login.

It was working fine till last two days. Now in IE11 on Windows 10 users are getting exception while logging in via SSO in production environment.

Below is the error users getting in the browser.

Status: Fail

Message: There has been an issue; please consult your system administrator

....

and in the logs we see cookie exceptions shown below.This is happening only with IE 11 where as chrome and Edge are fine. Application is running on JBoss and Oracle DB
