Tinc no start as service

[pr0j3ctx at gmx.net]

Hello.

I am using tinc for some years now. Since I migrated my OVH VPS from 
Strassbourg to Limburg with Debian 9 tinc don`t start as Service.

Because of the VPS i use systemctl commands, but it uses the init 
scripts instead

I copied the same config. But it doesn`t start as service. If I start 
tinc with "-n <netname>" from console it all works like it should be.

The problem is that i get no info in the syslog. It shows the start of 
tinc, but not the start of the net. But thats all.

Is there a way to get more information why the start fails?

Hopefully,
