Incremental materialization, Service Account getting locked out

The problem I’m having

When I run an incremental model overnight, my designated dbt Service Account gets locked out due to multiple failed sign-in attempts. This never happened until we started incremental a couple of days ago, but it is now consistent twice in a row on the overnight runs, as well as some Master runs we do during the day. Has anyone else noticed this? The problem is, the issue is inconsistent. I have gotten the issue inconsistently occurring in both dbt cloud and dbt Core when running models

Credentials for db Cloud have not been updated recently, this just happened out of the blue

Some example code or error messages

250001 (08001): Failed to connect to DB: Your user account has been temporarily locked due to too many failed attempts.
