HPE Switch RADIUS authentication no longer working

For whatever reason, all of our HPE switches (ProCurve / Aruba) no longer allow you to authenticate in with RADIUS. Our NPS server, which is on Windows 2016, and I have not been able to identify something in the log that may be contributing to this. The switches are on multiple different subnets, some reside directly on the same subnet as our NPS. Firmware wasn't recently applied to any of the switches either.

I realize this is pretty vague, but has anyone ran into a similar situation where it was working and then stopped? If so, what did you do to resolve it? I'm leaning towards the NPS server or something with a certificate, but I'm looking for advice.
