Our client uses the anyconnect VPN for remote work.  I recently created a 2019 Server Domain controller and moved all the roles to it so i can get rid of the 2012 server since it is now end of life.     Now they cant connect through the VPN after pointing its authentication to the new 2019 DC.  If i point it back to the 2012 server it connects just fine.     Currently getting this error.  msg: Peer IP=xxx.xx.xxx.xx Peer port[31641] AAA[1]: AAA authenticate failed retval=9 - Authentication service cannot retrieve authentication info   Meraki help ran packet captures and helped troubleshoot the issue and said that i am getting tls errors and need a certificate uploaded.  Then sent me this link. https://documentation.meraki.com/MX/Client_VPN/AnyConnect_on_the_MX_Appliance/Authentication#Active_Directory_Authentication   Not sure how that link helps truthfully.  Anyone have any ideas?  Anyone else have these issues after domain controller upgrades since 2012 just went to end of life?  How did you fix it? ...
