Gray box over "Clef"

[rdono61]

Running MinimServer on Synology 214+, with MinWatch 8.2, update 23, on an iMac.
1. Just returned from 2 weeks away, started computer, and MinimServer seems to be off. The "clef" icon on my Mac has a dark gray box over it, and when I click on it all the menu items are grayed out except Options, Refresh, and Exit. Plus my Auralic Lightning app says there is no connection to the server, but the Synology says it is working fine and I was able to download their latest update.

2. dumb question, but how do you tell if MinimServer is operating properly?

Thanks for any help.
