Do you have more than 1 connection server? I have in the past worked with support and they had me power down the Connection servers and then power them all back on to get them synced up.
This KB you can do the same thing using the CLI commands.
Many Thanks for your response @vBritinUSA
kindly note that the replication is working well, and the command has been executed successfully.
but my problem, i think between the composer and the connection server.
