This certificate validates that the network you are connecting to is provided by the University. You may need to take action on each device you connect to the wireless network (eduroam) or to the student wired network.
For devices that have been configured using the UoY Setup, eduroam CAT, or geteduroam tools, you should not need to do anything at all.
For devices that have been configured manually by simply entering your username and password, you may see a message similar to this (the screenshot below was taken from Windows 10):
If you expect to find eduroam in this location, go ahead and connect. Otherwise, it may be a different network with the same name.
Some devices may ask you to accept a new certificate. You should confirm that the certificate serial number and fingerprint displayed matches the details below (eg with the “Show certificate details” link in the above screenshot) before accepting it. If this is the case and the device connects successfully there is no further action required.

However, if you aren't able to connect then you will need to forget the network entirely and repeat the setup process:
"Legacy" Windows devices managed by Active Directory won’t require any changes. Devices managed by Azure AD might require users follow the instructions above for unmanaged devices.
Follow the instructions above for unmanaged devices to get reconnected.
