Workbench connects remotely but cannot connect from same PC with MySQL ODBC 5.1 Driver

[Dan E]

This has worked previously for over a year. Now, my VB app cannot connect to the remote MySQL DB.

To troubleshoot, I installed MySQL Workbench. It connects remotely fine. I can query, etc all as normal. I believe this confirms all firewall, routing, IP, port, security, authority and such issues are NOT the problem. Am I right?

My application, however, fails with the call to cnMySQL.OPEN() with this error msg:

[MySQL][ODBC 5.1 Driver]Can't connect to MySQL server on '##.##.##.##' (10060)

Next, I ran an ODBC trace. Everything in the trace works with the exceptions below:

TubsVB 1454-2534 ENTER SQLDriverConnectW

The MySQL workbench does not use the ODBC driver so I cannot compare it's connection through the ODBC trace log ;-(

Obviously, I would love a solution, but if not that, how to proceed with tracing/problem isolation so I can figure it out?

Thanks to all for any tips, suggestions or solutions.
