I am able to connect my DB from other nodes as well as from haproxy node but not able to connect via my VIP.

ERROR 2013 (HY000): Lost connection to MySQL server at 'reading initial communication packet', system error: 0

• the port is active listening at 3306 from all nodes.
• privileges has been given for the DB to access using haproxy,
• port 9200 is been added in all node /etc/ssh/sshd_config file,
• mysqld:ALL has been appended in all node /etc/hosts.allow files.

Need help to find the root cause. Thanks for all your brain in advance.
