@Mathava_Selvan HI Selvan… Welcome to the Percona Community.

As per the error log, I see "Connection timed out” is the main error. So, Check firewall connections, se-linux or other networking access.

Also, Please verify that the following ports are open: 3306, 4444, and 4567 which are required for MySQL and PXC cluster connections.

Finally make sure to keep your wsrep parameters / wsrep.cnf to use by PXC.
