Minim Watch cannot find MinimServer

[jacobacci]

My MinimWatch icon remains grey. It used to turn green indicating everything is ok.
My configuration is as follows:

• Synology DS1815+ running latest DSM and MinimServer 0.8.5.3 update 129 and MinimStreamer 0.7.14. MinimServer is shown as "running" on the NAS
• Windows 10 1903, Java 8 Update 231. MinimWatch icon is there, but grey. The context menu only shows three entries in bold: Options, Refresh and Exit
  

MinimServer itself seems to work. I can access it from Volumio on a Raspberry Pi

This is probably caused by a recent Java update on your Windows PC breaking the firewall rules that enable MinimWatch to communicate with MinimServer. You can fix this by following the instructions in this post.
