Users are having issues reconnecting to sessions open for over 10 hours. Customer is seeing thousands of these errors on their VDAs: [S107] HdxCredentialSelector::PerformCertificateHash() Failed: [Error: Access Denied (FAS server 'us007xx-cfas01.cloud.xxxx' correlation: 330a453d-1db5-4b0e-9571-485de43xxxxx). It seems as though once 10 hours has passed, there is some Kerberos issue between FAS and the profile management solution where the user cannot access the mounted profile disk.
AD is not able to re-issue the kerberos token
