[Nut-upsuser] Synology NAS is shutting down Ubuntu servers after very brief power outage (fwd)

upsmon.conf on server: https://pastebin.com/z4CrUTxb
nut.conf on server: https://pastebin.com/540ShZH7
Permissions for /etc/nut: https://hastebin.com/qecolodapi.diff
On the Synology (I didn’t edit any of these files):
I don’t think I am able to run that script. If you can, I wouldn’t know how.
Please let me know what you think.
Thanks for all the help!

> APC Back-UPS NS 650M1 UPS ---USB---> Synology NAS (DS416 - Master?) ---Ethernet---> Netgear Managed Switch w/ uplink to router <---Ethernet--- Servers (Ubuntu 20.04 - Plex, Pulsar, Proton - All three set as slaves)

> So what I have done so far is enable the "Network UPS Server" on the Synology, entered the three IPs of the servers in there, set it to shutdown when battery is low and enabled "Shutdown UPS when the system enters safe mode". I then installed NUT on all three servers. In nut.conf I changed MODE to "MODE=netclient". I then added my MONITOR line in upsmon.conf. on all three. Looks something like this:
> MONITOR ups at 192.168.1.70 1 monuser secret slave
> My SHUTDOWNCMD looks like this:
> SHUTDOWNCMD "getUPSstatus ups at 192.168.1.70 ; logger -t upsmon.conf \"UPS status is $UPSstatus\" ; /sbin/shutdown -h +0"
> Would that not work? I believe that's what you told me to put there.
> I think I've definitely made a mistake though, in that I have not set RUN_AS_USER in upsmon.conf and set up the appropriate permissions. I read somewhere that it would then run as user NOBODY and not be able read upsmon.conf. Is that true? Could that be the whole problem?
