SQL 2017 DAG configuration

HI

I am trying to configure SQL Server 2017 Distributed Always-On Groups (DAG) from DC1 to DC2 using below steps.  In AG_DISTRIBUTOR, the CLUSTER2_LS - SECONDARY is showing red mark, due to this i am not able to replicate db from DC1 to DC2. Can you please review below steps and correct me with correct steps.

I have executed WSFC validation report, not found any errors in cluster setup.
