Dear Friends

Recently we configured 3 tier architecture (NAVSERVER, SQLSERVER & IIS Server on separate machines).
As per Microsoft documentation SPN registered & delegation setup done.

SPN
setspn - l domain\serviceaccount

ServerInstance/navserver:7046
ServerInsatnce/navserver.domain.com:7046

Delegation
DynamicsNAV navserver 7046
DynamicsNAV navserver.domain.com 7046
HOST navserver
HOST navserver.domain.com

But still we are getting the below error

'A server error has occurred, and the content cannot be displayed. Refresh the page or open a new browser window.'

Below is the event viewer message.

    Reconfigured the delegation setup and tried disable the Use Kerberos Only option. Now working.
