Hi
Got a bit of a weird problem. I have an iAP cluster where we host a Guest SSID making use of the iAPs internal Captive Portal.
Asof lately more and more people are getting a certificate error and not allowing them to continue or ignore the warning - meaning none of them can connect to th Guest SSID as they cannot access the Captive Portal page --- IE and Edge are the biggest culprits as Firefox appears to work.
Checking the certificate through Firefox I can see that certificate is signed by Geotrust with an expiration only in the next few years (it is the default iAP cert)...
Any ideas are welcome on why we would get Cert errors on the Portal through some browsers and not on others and how to correct the error on the other browsers?
