Confluence upgrade error - 6.15.9 to 7.4.3

[informatique]

Hi,

I'm tring to upgrade Confluence Server 6.15.9 to 7.4.3, but Confluence stills down after the migration.

What i've tried:

- Upgrade Confluence 6.15.9 to 7.4.3: KO
- Upgrade Confluence 6.15.9 to 7.0.5: It works perfectly
- Upgrade Confluence 7.0.5 to 7.4.3: KO
- Upgrade Confluence 6.15.9 to 7.4.3 with Docker: KO

I have that error on the landing page:

Database: Database connection failed

The database (MSSQL) is up and the configuration is correct.

This error appears in my catalina.out:
