I forgot to mention the reasoning. From your proton and plex logs:

|Aug 11 16:37:40 proton upsmon[1554]: UPS ups at on battery 
Aug 11 16:37:45 proton upsmon[1554]: UPS ups at on line power|
|Aug 11 16:38:10 proton upsmon[1554]: UPS ups at forced 
shutdown in progress|
||Aug 11 16:37:43 plex upsmon[974]: UPS ups at on battery Aug 
11 16:37:48 plex upsmon[974]: UPS ups at on line power Aug 11 
16:38:13 plex upsmon[974]: UPS ups at forced shutdown in 
|So nut on Synology believes that it is a good idea to trigger a FSD 30 
secs AFTER switching back to line power when in fact it should CANCEL 
any shutdown in progress. Unless you have the willingness to search & 
fix whatever stupidities they do in their unorthodox use of nut... just 
use a sane version |
