local certificate authority expired on windows server 2012R2, renewed, but still not working

I am using a radius server, and my cert on my server expired.  I renewed it, but it's not taking effect. I restarted the cert service, but still no go.
What am I missing?

When I log into my smart phone, or windows pc, any device, it's failing to connect because my cert is expired.  See pictures below.
What else do I need to do?  Since I'm using a radius server, I don't know if I should delete this cert and create a new one, as it might have issues pointing to the wrong cert?

I keep on trying to connect on any device and still displays the old expired cert.

Make sure that the root certificate is copied to your device to ensure that new certificates are trusted.
You can email the certificate to yourself, open email on your device and then you can download and install the root certificate.

But in windows 10, when I try to connect to WiFi, it just refuses the connection right away.

If I have to copy the very manually to each PC, that’s not going to work, I have over 80 or so PCs, and I can do that for each one.

should I delete the entire certificate and recreate it?  Would that be better?

That looks like the root cert, not the server cert used by NPS
Your help has saved me hundreds of hours of internet surfing.

How you also renewed any other certificates esp for NPS and installed it. It may still be using the old certificate on the NPS server!

So how do I resolve that? Where would I look to see which very it’s using?
