Setting up AlwaysOn AG from Primary to 2 secondary replicas. Both async.
Primary to replica1 works fine and completed setup.
Primary to replica2 gives below errors.
On primary (LABSVR6)
--------------
A connection timeout has occurred while attempting to establish a connection to availability replica 'LABSVR8' with id [99F3037B-D00A-4421-AA3E-0E1FEAD28CDA]. Either a networking or firewall issue exists, or the endpoint address provided for the replica is
not the database mirroring endpoint of the host server instance.
On Replica2 (LABSVR8)
--------------
A connection timeout has occurred while attempting to establish a connection to availability replica 'LABSVR6' with id [B3F0C0F0-3742-4607-89F7-88197334E802]. Either a networking or firewall issue exists, or the endpoint address provided for the replica is
not the database mirroring endpoint of the host server instance.
And when trying to join manually through Management Studio, it says:
Failed to join the instance 'LABSVR8' to the availability group 'SQLAG'. (Microsoft.SqlServer.Management.SDK.TaskForms)
Failed to join local availability replica to availability group 'SQLAG'. The operation encountered SQL Server error 41106 and has been rolled back. Check the SQL Server error log for more details. When the cause of the error has been resolved,
retry the ALTER AVAILABILITY GROUP JOIN command. (Microsoft SQL Server, Error: 41158)
Both using same domain service account for startup - which is anyways added with SYSADMIN.
Primary to replica1 is working fine.
Primary to replica2 is having above problem when joining.
Any suggestions?
TIA
