MySQL for Excel error

[Francisco Ignacio Fernandez Sanchez]

When running MySQL for Excel in Excel the following error occurs

Connection attempt failed

The key provided is not found in the dictionary.


Both MySQL and Excel are working and I can access from Excel to MySQL via ODBC.

I have disabled Firewall and Antivirus and it gives the same problem, reinstalled connectors and MySqServer, in the logs I do not see any related error.

With the user and password I can access from the Workbench and from other Data Sources via ODBC in Excel itself, the problem is only in the MySql for Excel component, I have tried with other previous versions and also give the same problem.


Does anyone have any idea what could be the problem?


The versions of the installed components are:

Windows 11 Home 24H2

MySQL Server MySQL Server 8.0.40

MySQL For Excel 1.3.8

MySQL Connector ODBC 9.1 (64 bits)

MySQL Connector NET 9.0.0

Microsoft® Excel® para Microsoft 365 MSO (versión 2411 compilación 16.0.18227.20082) de 64 bits
