IPv6 & Apple

Hi Charles:

The app makes database calls using the following structure.

put "198.01.234.56:1234" into tDatabaseAddress
   put "dbname_" into tDatabaseName
   put "dbuser" into tDatabaseUser
   put "dbpassword" into tDatabasePassword
   put revOpenDatabase("MySQL", tDatabaseAddress, tDatabaseName,
tDatabaseUser, tDatabasePassword) into tResult


I have ATS disabled in the standalone because we don't currently have an
HTTPS server. The error displayed in Apple's screenshot was my simple
error message stating it was unable to connect to the database.  I need to
go back now and figure out if there's some missed issue with the code.
But it concerns me if Apple is testing the app in some way that I don't
have a means to reproduce.  I'm not very knowledgable in server matters so
any advice is appreciated.


Thanks & Regards,
