Guest dissconection issues for Contractor profile more than 6 days

[Noovi]

Hello Guys,
We are running wireless setup with foreign and anchor WLC setup and sponsor portal hosting on ISE with L3 on firewall.

Guest users are able to connect SSID and when we select profile on Sponsor portal (Profiles confgured on ISE) as Daily, Weekly and Contractor with 5 days, users authenticates properly and uses guest/internet network with no issues.

However, when we select Contracto profile with more than 5 days (for example 7days or more), user authenticate initally and gets guest access for approx 1mins and then getiing login page again.

We have checked with ISE TAC but they are saying nothing abnormal from ISE end.

Anyone has this issue seen or any suggestions here?

 - As per https://www.cisco.com/c/en/us/support/docs/wireless/wireless-lan-controller-software/200046-tac-recommended-aireos.html , use latest advisory : 
                    https://software.cisco.com/download/home/286284738/type/280926587/release/8.10.190.0

  And check again , (the aireos based platforms are getting older , nowadays it becomes more and more good practice to use the latest/last release available for the particular model)
