In a device group, iApps LX applications fail to sync to the other devices. In restjavad.0.log you notice this log entry, approximately once per hour: [8100/tm/shared/BIG-IP-failover-state BIG-IPFailoverStateWorker] Failed to discover [address]: java.lang.IllegalStateException: Authentication Failure to host [address]. Please check the credentials provided.


If you do not have iApps LX configured, there should be no impact other than the warning in restjavad.0.log which you can safely ignore. If you have iApps LX configured and the iApp is not syncing, then this will impact traffic if a failover event occurs.


- This occurs after upgrading devices in a device group from 12.1.1 to a version higher than 12.1.1, such as 12.1.1 HF1. - It can also occur on UCS restore. - This occurs after upgrading devices in a device group from 12.1.0 to a version higher than 12.1.0, such as 12.1.0-HF1 (or above). - Also found this can occur with a clean install of v12.1.2-Final and upgraded to v12.1.2 HF1.
