We have two active/active Pulse Connect Secure clusters in two different data centers. ~ 3000 users connected to each. Less than 20 users cannot connect to one of the clusters but can connect to the other cluster. At one time the users were able to connect to both. We rebooted the cluster and cleared the user database. User still unable to connect. Has anyone seen this before? Client 9.1.10, PCS - 9.1R12. Issue was the same on 9.1R11.
