Hi,

your issue is most certainly that you are using MySQL. The [version 11](https://docs.mattermost.com/product-overview/mattermost-v11-changelog.html) has removed support for MySQL.

> - Support for MySQL has ended. Our [Migration Guide](https://docs.mattermost.com/deployment-guide/postgres-migration.html) outlines the steps, tools and support available for migrating to PostgreSQL. See more details in [this forum post](https://forum.mattermost.com/t/transition-to-postgresql/19551).
