Getting pymysql.err.OperationalError: (2013, 'Lost connection to MySQL server during query')

[Mike Bowerman]

I am running a Python script in a GCP Compute Engine VM to connect to the MySQL instance, and I am getting this error. I am using pymysql for connection. I tracked the error to this file 

`/usr/local/lib/python3.5/dist-packages/pymysql/connections.py` line 703, in _read_bytes and to the following lines of code

```

if len(data) < num_bytes:

        self._force_close()

        raise err.OperationalError(

        CR.CR_SERVER_LOST, "Lost connection to MySQL server during query")

```

Has anyone experienced this issue before?
