Users are not able to login in application, after deleted cookies from client browser they get in

We are getting login issues after enabled SSO in tenant level, it was working fine for 7 days but suddenly today all our user are not able to login in application. after deleting in client browser most of them are able to login but some of them still not.

We have set SSO expire limit for 7 days as default , it means SSO cookie is been expired today might be that is the root cause.
