could you explain why not sending "a delayed command to the UPS to turn it off"
may cause that issue?
You need to stop the UPS from beeping. Only then can you get a clear
restart when power returns. To stop the UPS from beeping, you must turn
it off.
ups.delay.shutdown: 20
ups.delay.start: 30
is it something related?
Yes, they are related: the two ups.delay values are used by the program
which turns off the UPS. This program is called by by script nutshutdown
which is part of the nut package. Do you have this script installed?
What does command "systemctl status nutshutdown" report?
