Hi @AneeshBabu
Is this the same case as Not able to add the node 2 to the cluster - PXC 8.0.27 - #12 by vadimtk ? @vadimtk noted that your gcomm_address line uses IPs in the 192.X range while your error log show you are using IPs in the 172.X range.
If your database nodes have multiple IP addresses then you should set this using wsrep_node_address so that PXC knows on which address to listen/send PXC cluster traffic.
