SCCM service broker

Primary site server and the replica of the primary site server are connected via AlwaysON.

AlwaysOn works fine. Failover , Failback everything is fine.

Once after alwaysON is enabled, getting the bellow message in SQL error log.

Message
Service Broker login attempt failed with error: 'A previously existing connection with the same peer was detected during connection handshake. This connection lost the arbitration and it will be closed. All traffic will be redirected to the previously existing connection. This is an informational message only. No user action is required. State 80.'.  [CLIENT: 10.168.45.140]

Can anyone please let me know what this message means? as the SCCM team is not ready to move forward without resolving this error.

Many thanks for all your help in advance.
