This is the human-readable remote error description for this specific FSM run, corresponding to the error code above. An admin reviewing a history of failed sync attempts for one troublesome endpoint reads this text across several FSM run records to see if the same peer-side complaint, such as object not found, recurs every time, which points at a persistent underlying misconfiguration rather than a one-off glitch. If three consecutive FSM run records for the same endpoint all show 'Remote invocation timed out' here, that pattern suggests a connectivity problem between the fabric interconnects rather than anything wrong with the VLAN configuration itself.
