[SerUsers]: Mysql DB at different machine

Hi All I am trying to implement ser database (mysql part) on different machine. Ser is installed on machine say 'A' and Mysql DB is on 'B'. In ser.cfg I changed url to connect to database everywhere in ser.cfg file with machine B's ip (eg. modparam("auth_db|permissions|uri_db|usrloc","db_url", "mysql://ser:heslo@10.25.117.86/ser") n in rest too). But I am getting the following error when I checked ser logs: Nov 10 14:12:40 vm01 /usr/sbin/ser[12979]: get_connection(): Connection not found in the pool Nov 10 14:12:40 vm01 /usr/sbin/ser[12979]: new_connection(): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) Why it tries for local Mysql sock??
