DSM 6.2.4-25554 quietly broke my the enable network UPS server
Updated from 6.2.3-25426 Update 2.
Noticed when updating my ESXI hosts that upsc was not working.
getting the following Error: Connection failure: Connection refused
Checking Control Panel>Hardware& Power>UPS
All looks okay. But when going to SSH i noticed the file
/usr/syno/etc/ups/upsd.users
was blank.
I had to temporarily disable the Network UPS server hit apply
Then re-enable it and re-add my ESXI hosts' IP's and hit Apply. This regenerated the file correctly.
All is now well. May want to check yours and make sure its working. You can do that if you have the Nut Client installed on ESXi and cd to
cd /opt/nut/bin
Then run
./upsc ups@ip-address
where ip-address is the IP of your Synology NAS.

Yes, that's what I noted during the update. removing the IP of the "Permitted Synology NAS Devices" and adding it back did the trick.
You are warned on ssh anyway when the other servers can't connect to your nut host
Makes sense. Assuming you regularly ssh into your nas or esxi hosts (in my case. I don’t have others on these. ). The issue is I don’t, I only use ssh if/when I need it. I just happened to catch it because not only did I update DSM recently. I was also updating my hosts which generally require time to add/remove nut clients for VMwares update manager to work.
