we have 1 CAS and 4 Primaries in our environment and had recently updated our sccm environment from 1602 to 1610. we are facing replication issues in CAS and one of the primary sites. On CAS every things seems to be OK but on one of the primary sites it shows replication link in failed state.
On bit digging down replication group CloudProxy is in failed state and RLA is in degraded state. On initiating replication analyzer, CloudProxy become active but RLA remains in degraded state and after some time link again failed.
