Config-Sync not successful after failover to backup node

Hello All
Recently we have issue on config-sync in Solace HA setup. solace usual setup with primary / backup / Monitor.

there is no issue with Redundancy, when we move primary to backup.
The same time Config-sync show down one of the environment.

same setup with 5 set of solace HA was up and running no issue.
except the one set of solace HA have issue on its config-sync.

installation and configuration steps are same as the similar working environment.

solace1> enable
solace1# configure
solace1(configure)# hardware message-spool shutdown
All message spooling will be stopped.
Do you want to continue (y/n)? y

solace1(configure)# redundancy
solace1(configure/redundancy)# switchover-mechanism hostlist
solace1(configure/redundancy)# exit

:

solace2(configure)# redundancy
solace2(configure/redundancy)# group
solace2(configure/redundancy/group)# create node solace1
solace2(configure/redundancy/group/node)# connect-via solace1.solace.come.com

after set up all 3 node, we did validation for faiover

solace1> show config-sync

Admin Status : Enabled

solace2> show config-sync

Any Idea, currently we are running with work around
with option inside the group using ip

with all the three node
solace2(configure/redundancy/group)# create node solace1
solace2(configure/redundancy/group/node)# connect-via 192.168.132.3
solace2(configure/redundancy/group/node)# node-type message-routing-node

    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.

    Hello Tom
    Happy thanks for the update. Yes if we make good state config sync then make solace1, as primary again it work for it, but, when we check manual release activity also for primary reboot will move redundancy to backup this is normal behaviour redundancy.
    Then after config sync back again the situation i share before like that, I thought you guys meet this before, but wonder your side as well new. OK I will do it again this week will let you know anything positive new.

    Same time any other suggestion, then kindly share.
    Thanks again for the quick replay.
