We have multiple sites and employ a mixture of MR42 and MR62 WAP's managed via Meraki Cloud.
Users trying to connect to an SSID on a new site are getting a Windows Security Alert: 'The connection attempt could not be completed' message with the following details:
Radius Server: radius.meraki.com
Root CA: COMODO RSA Certification Authority
The server "radius.meraki.com" presented a valid certificate issued by "COMODO RSA Certification Authority", but "COMODO RAS Certification Authority" is not configured as a valid trust anchor for this profile.
There are options to Terminate or Connect but the Connect option does not lead to connection.
I have checked and all the settings I can see are identical to our other sites that are working fine.
