The NUT server is my Synology NAS (DS416). Client is communicating with server (confirmed by running "sudo upsc UPS@[Your_IP]”). It receives events when I manually pull the power plug and shuts down properly when I do a forced shutdown (by doing “sudo upsmon -c fsd” via telnet on the NAS).</div></div><div class="bloop_container"><div class="bloop_frame"> </div></div><div><br></div>The problem is when there is an actual brief power outage of a few seconds, maybe 5 - 10 seconds max. The NAS stays powered up, however the Mac mini (NUT client) shuts down. When booted back up it immediately shuts down again. It will keep shutting down as soon as it boots up in MacOS and will keep doing that until I reboot the NAS. I’m not sure if the problem is the client or server, however I’ve been talking to Synology Tech Support and this was their last message:<div><br></div><div>"Can you please check the NUT settings on your Clients and make sure that there is enough of a delay/wait period after it gets the signal.”</div><div><br></div><div>What delay are they talking about? I have looked through the upsmon.conf and am not sure if anything there is the appropriate delay to adjust. Does that even seem right? Is the problem with the client or the server? I can paste my upsmon.conf and any logs if necessary. Any help would be greatly appreciated. Thank you.</div><div><br></div><div>Regards,</div><div><br></div><div>Todd B.<br></div></body></html>
