The above issue might occur if time difference between Master and the storage node on which user data resides is more than 120 seconds. This is because inSync only allows a time difference of up to 120 seconds UTC between Master and Storage Node irrespective of the time zone.


Check the system time on the inSync Master and the Storage node to make sure it is accurate according to their time zone. If there is a time difference, ensure that the time difference between inSync Master and the Storage Node is not more than 120 seconds UTC. 

In case the error persists for more than 24 hours, please reach out to Druva Support for further assistance.
