SQL error when trying to start a NAVService

I'm getting a SQL error when I try to start a NAVService. All settings seem to be fine. It looks like it is database related.
The NAV version is: NAV2017, build 10.0.25480). I tried the NAVServices for SQL2014 and SQL2016, but same error.
This is the error I'm getting:

Server instance: SCSPROD
Tenant ID:
<ii>The Cannot access a disposed object.
Object name: 'NavSystemTenant'. instance startup is aborted and the event publisher initialization has been cancelled.
20</ii>

I made sure ports are not being used by other services.
Anyone has an idea?

Thanks,
Roelof
