zabbix proxy auto start

[SchylgeICT]

I have installed zabbix proxy.
Manual it starts with:
sudo service zabbix-proxy start

then after:
update-rc.d mysql defaults
update-rc.d zabbix-proxy defaults

it does not start after reboot. Zabbix-proxy is located in rc2,3,4,5.d
if i try:
sudo ./S01zabbix-proxy start
it fails with:
[....] Starting S01zabbix-proxy (via systemctl): S01zabbix-proxy.serviceFailed to start S01zabbix-proxy.service: Unit S01zabbix-proxy.service not found.
failed!

starting again with "sudo service zabbix-proxy start", works fine.

running debain stretch ARM.
any idea? Kinda stuck here...

forget it. it was pretty simple actually.
i used update-rc.d again to remove zabbix-proxy and then added it again. now it starts at reboot...
