Exchange Server 2013 on prem OWA blank screen after logging in

Hi manuphilip ,

Thanks for your continued support.  I went through windows event log and exchange event logs but can not see any errors with SSL in them.  I am not sure if these errors are relevant but i can see the following:

MSExchange Management Logs

Cmdlet failed. Cmdlet Get-UserPhoto, parameters {Identity=Jordan.Yap@afgroup247.com.au}.

Cmdlet failed. Cmdlet Get-MailboxDatabaseCopyStatus, parameters {Identity=Mailbox Database 1063958844\*, DomainController=AFSERVER.anytime.local}.

Active Directory Webservice Logs

Active Directory Web Services could not find a server certificate with the specified certificate name. A certificate is required to use SSL/TLS connections. To use SSL/TLS connections, verify that a valid server authentication certificate from a trusted Certificate Authority (CA) is installed on the machine.

Certificate name: AFSERVER.anytime.local

Is there any particular log file i should be checking?

Regards,

Mark
