Description:
Workbench 6.3.3 connects successfully to SQL server hosted in Hostgator where I can see all database schemas and sometimes tables, but when I trie to execute an SQL statement in tables (SELECT * FROM db.table) this errors appear:
ERROR 2006 : MySQL Server has gone away
ERROR 2013 : Lost connection to MySQL server during query

How to repeat:
Connect Workbench to MySQL Server hosted in Hostgator. Create some tables, then execute the SQL statement.

Suggested fix:
I downgrade to Workbench 6.2.5.0 build 397 it works fine for now.

Thank you for the bug report.

I was able to repeat after some hours in idle condition I checked after 8 hours however could be less time on idle status.

Please check with mysql.exe client command prompt if you get the same behavior than WorkBench. Thanks.

This is also happening on MySQL WorkBench 6.3.5 on Windows 10 connecting over SSH tunnel on a Digital Ocean server.  MySQL is not exposed publicly so tunneling is necessary.  This may or may not be part of the issue.  Perhaps SSH is what is terminating the session?

Having this issue on Windows 7 and MySQL Workbench 6.3.6 build 511 CE.  I've tried increasing the DBMS keep-alive setting in the workbench preferences to a very high number, but it still disconnects from the server frequently (after several minutes of inactivity).

I get exactly the same problem using the following. 
- MySQL Workbench 6.3.6 build 511 CS 64bit on MS Windows 10 
- Connecting to Hostgator

For the record, it provides the error message for any submission sent almost immediately after connecting. In other words, I connect successfully. Then, submit an SQL. It gives the error. 

I uninstalled Workbench 6.3.6 build 511 CS (64 bit), and installed version 6.2.4.12437 build 2427 (64 bit). It worked smoothly, using the existing connection settings.
