Failure of the motorway E - there are network connectivity problems or this peer has different support encryption (AES / non - AES software)

I have two websites and a cluster CPU as below:

site - 1

CUCM pub-1

Pub 1 CUC

imppub

exp-c-1

exp-e-1

site-2

cucm2

CuC2

IMP2

exp-c-2

exp-e-2

I do a bunch of highway E and C, but it I show error on cluster of highway E:

Failure - there are network connectivity problems, or this peer has the support of different encryption (AES / non - AES software)

This highway is part of a cluster, but is not the master of the configuration. Configuration changes made on this highway may be lost. More information about the Clustering help page.

What is the solution to fix it?
Locally add cluster of highway or having to make cluster of 4 motorway between locations?

How far are the peers of the highway on the other, what is the round trip time?  This should be within 30ms.

Can you confirm that all highways in the cluster have the same keys option installed on all peers, as it is a requirement, call license quantities can be different, but the features option enable/disable keys must be the same.  Additionally, make sure that the version of the software installed is the same, that you have a version mismatch or could be active where encryption the other not.

Regarding the "this highway is part of a cluster, but is not the master of the configuration... '. "this message is normal for a node that is not the master, as it is said just only make changes on the master, since all changes on the slave will be replaced by the master.

Suggest you watch on creation of Cluster Expressway and maintenance Deployment Guide (X8.8) in case you have not yet.
