    I'm not able to connect to the switches via Putty or the web UI (443) today.  I was able to 2 days ago.

    Looking at Wireshark for clues, I noticed this while trying to connect to 10.0.0.6 (Aruba switch).  

    I also see this on the event log on my NPS server.  So is it a certificate issue or NPS?  No changes were made to NPS.

    Usually I login to switch via RADIUS / Duo.  Now the only way I can login is if I disable the Duo service, and login as manager.  Then I checked the self-signed cert on the switch, and its not expired

    I do have a CA server, and when I look at the even viewer on there, I also see this.  I filtered it in the Event Viewer by ID, and it started on 12/8

    Download an old Browser (Old Chrome or Safari). Then you can login and change the certificates.

    I had a similar issue and it worked for me.

    Already tried other browsers, and can't SSH.  I rebooted my NPS server, and now I'm able to login via RADIUS again.

    So it was not a SSL Issue, but rather a RADIUS Issue.
    Great that you got it fixed.
