Subject Re: ManifoldCF Docker MySQL Connection Error
Date Sat, 24 Nov 2018 12:42:17 GMT
Hi Furkan,

The only thing that comes to mind is that maybe your MySQL is running on a
different port than you expect, or that the MySQL driver you are using is
not compatible with your setup.  Basically it is failing to create a
connection between the driver and the database.
