Hi @venkatn80, I don’t think I’ve ever seen that one before, so I can’t personally give you a likely reason for it. You seem to think that using IP address rather than hostname has affected config-sync, is that right?
I think the easiest thing to do would be to get config-sync in a good state. Can you bring solace1 up, enable redundancy, then make solace1 primary. Then examine the config-sync state on both solace1 and solace2. That will give us a starting point for going further.
