Error while SQL migration

Hi all

I have a self hosted Bitwarden Instance.
I have migrated the MSSQL-Database away from the docker-container into my full MSSQL-Instance with this manual
https://bitwarden.com/help/external-db/

Now i got a issue when i would like to update the bitwarden instance. Everytime i got an error while the database migration procedure is runing.
The same happens when i do ./bitwarden.sh updatedb

Imo, there is no connectivity problem to the SQL-Database. Bitwarden itself is running fine.
I could imagine, that the db-migration process is not expecting external Databases.
Do somone has some inputs to me?

Many thanks
