We have 8 databases in an instance. All 8 databases are members of Availability Group. On the secondary replica, the whole instance is not synchronizing . Could you please advise how to bring the secondary instance as synchronized
Thanks,

Have you checked for error messages in the SQL Server error log? The cluster logs? (Or is this a clusterless AG?). How is authentication set up for the AG? Certificates? Logins? What does SELECT at-at-version say on the two nodes?
