check if your admin certificate expired

Yes, this will show any certificate for admin portal.

Out of curiosity, does the deployment view you posted a screenshot of ever load?

The login issue you described is most commonly seen when someone or some backup tool tries to take a vm snapshot of ISE. ISE will hang and when you try to log in to the CLI, you receive a credential prompt, but when you log in nothing happens. The GUI would not be available if a snapshot was done. The only option after a snapshot is to power cycle the VM from vcenter.

For what it's worth, one of the large 2.4 deployments I monitor with 150k active endpoints can take ~30 seconds to load all widgets in the dashboard. It only takes 2.5 seconds to load the deployment view with 21 nodes.

Performance related issues can be caused by any number of factors. If you haven't already you will want to open a TAC case, this is likely not something you will find the root cause for without submitting a support bundle.
