Recently upgraded all 4 of our ACS appliances 5.8.1 and patches. All four stopped allowing access to the GUI around the same time. Users are still able to authenicate and i can access the CLI. Thoughts?
It may be that the Management services is not running or unresponsive after the upgrade. If you run the command "show application status acs" command, what is the output? Also, use the "show disk" command to check the disk utilization status.
If you see the management service not running, try to restart the services on the node or reboot the box.
If you are still facing issues, then you might need TAC assistane to go through the logs or access the root.
