Error message on Nightly Backups

I use Enterprise manager to run backups on our database, one backup is stored locally and one goes to the cloud. Both backups are dying every night to Error evaluating parameter sources/security checks/locks ORA-20224: Could not resolve instance for cluster/redundancy group <databaseName>:rac_database. I've tried restarting the agents on both of the oda nodes. I've tried restarting OMS. I've tried power cycling both database nodes. Nothing seems to resolve the issue.

Any recommendations would be great,

    Knowing the DB and EM version would help here.   You can try this, but if it doesn't resolve the issue, i would open an SR.   You can also test a regular job (sql select) against the target and see if that fails.

    Download here:   EMDIAG REPVFY Kit for Cloud Control 12c, 13c - Download, Install/De-Install and Upgrade (Doc ID 1426973.1)

    Usage here:  Note 421563.1 EMDiagkit - How to Use the Repository Diagnostics

    Run the command

    repvfy verify -level 9 -details

    Review the dump log ($EMDIAG_HOME/LOG/details<timestamp>.log) and verify if the following test numbers were reported:

    206. Hostname and EMD_URL mismatches (7507446): 1

    211. Redundant Master Agents defined for RAC (8638231): 1

    If so, run the following fix routines:

    repvfy verify targets -test 211 -fix

    repvfy verify targets -test 206 -fix
