Percona XtraDB Cluster Node is not synced. in remote server

MySQL & MariaDB Percona XtraDB Cluster 5.x

Hello dear friends
I’ve a problem with new node . I created new node and all of the configs is the same as other nodes and it synced by other nodes .
I used haproxy and mysqlchk script in xinetd for checking cluster in remote server ,
when I run :

/usr/bin/clustercheck

in local machine I got :

HTTP/1.1 200 OK
Content-Type: text/plain
Connection: close
Content-Length: 40

Percona XtraDB Cluster Node is synced.

till here all of things are good , but when I want to test from remote machine or run

telnet 127.0.0.1 9200

I got :

Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.
HTTP/1.1 503 Service Unavailable
Content-Type: text/plain
Connection: close
Content-Length: 44

Percona XtraDB Cluster Node is not synced.
Connection closed by foreign host.

in the local working well , but the response in remote machine is incorrect ,
in the log of clustercheck script shows :

Warning: Using a password on the command line interface can be insecure.
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (13)

how can I solve it ?

The problem was in /var/lib/mysql permission
to solve :

chmod 777 /var/lib/mysql

I would not recommend chmod 777 to the datadir, better check your error log to find the real problem.
