Does your SQL database string contain 127.0.0.1 or localhost?
https://dev.mysql.com/doc/refman/5.5/en/connecting.html
On Unix, MySQL programs treat the host name localhost specially, in a way
that is likely different from what you expect compared to other
network-based programs. For connections to localhost, MySQL programs
attempt to connect to the local server by using a Unix socket file. This
occurs even if a --port
<https://dev.mysql.com/doc/refman/5.5/en/connecting.html#option_general_port>
or -P option is given to specify a port number. To ensure that the client
makes a TCP/IP connection to the local server, use --host
<https://dev.mysql.com/doc/refman/5.5/en/connecting.html#option_general_host>
or -h to specify a host name value of 127.0.0.1, or the IP address or name
of the local server. You can also specify the connection protocol
explicitly, even for localhost, by using the --protocol=TCP
<https://dev.mysql.com/doc/refman/5.5/en/connecting.html#option_general_protocol>
option.
For example:
