Can't install confluent-control center

Question

I am new to Kafka and trying to install my ubuntu machine Confluent control center.
Here is the document i have followed : https://docs.confluent.io/platform/current/installation/installing_cp/deb-ubuntu.html
I've succesfully built kafka with 3 brokers and zookeeper but there is soem problem in Confluent Control Center.

When i start conf-cont-center

sudo systemctl start confluent-control-center

The log under the /var/log/confluent/control-center.log says that:

The state store, commander, may have migrated to another instance.
