Getting NUT (Network UPS Tool) Add-on to start

Needing help on that one.
Here is my configuration file for the NUT Add-on

Like you can see, the UPS is seen by HA in the NUT Add-on log
And I have tried with the following driver optional settings : bus, device, vendorid and productid.

Depending on what I try I get
This error : No matching HID UPS found
Driver failed to start (exit status=1
or that one : Trying to connect to UPS [[email protected]@localhost]
UPS [[email protected]@localhost]: connect failed: No such host
{“message”:“Event nut.ups_event fired.”}Network UPS Tools upsmon 2.7.4


I also tried with productid = 501 since its model is not well reported by HA in the NUT Add-on log. Here what I really have.
Connected to a Synology DS218+ NAS

Thanks for anything that could lead me to better understand the case.
