Grey icon of Minimwatch, Minimwatch does not see Minimserver

[Gijs Schubert]

Simon,
Thank you for your support. I did all steps 1)-5) above, and it still does not work with a fresh install of Java 8 update 211.

There are two odd events to mention:
a) since the problem started, MinimWatch never starts automatically after starting the PC, while it is in the start-up menu of Windows10. I have to start MinimWatch manually, which goes fine (but resulting in a grey icon).
b) after I uninstalled Java, removed all Java rules, and reinstalled Java, I checked the Windows Firewall inbound rules. Strangely enough, they do not show up there. I do not understand why inbound rules for Java are not added to the list after reinstallement. Could this block communication between MinimWatch and MinimServer?

In Norton I cannot find a set of firewall rules, so I cannot check if Java is mentioned. It could be that Norton simply uses the Windows Defender Firewall rules.

Anyway, I disabled both the Windows Defender Firewall and the Norton Security Firewall, and still the icon stays gray after rebooting the PC and relaunching, so there should be no blocking. A mistery!

After reinstallating of Java, MinimWatch gets launched and stays grey. The log message is:

MinimWatch 0.8.5.3 update 62, Copyright © 2012-2019 Simon Nash. All rights reserved.
Java™ SE Runtime Environment (build 1.8.0_211-b12)

In properties in field ohnet.subnet I have entered 192.168.2.0

It is worth mentioning that I use Firefox 64 bit version as browser, and that the Java website mentiones the following. Could this be related to the problem, or is this unrelated? It is probably unrelated, because I installed Minimwatch in October 2018 using Firefox 64, and it worked very well until 1 June (2 days ago).

Firefox no longer provides NPAPI support (technology required for Java applets)

As of September, 2018, Firefox no longer offers a version which supports NPAPI, the technology required to run Java applets. The Java Plugin for web browsers relies on the cross-platform plugin architecture NPAPI, which had been supported by all major web browsers for over a decade. The 64 bit version of Firefox has never supported NPAPI, and Firefox version 52ESR is the last release to support the technology. It is below the security baseline, and no longer supported.

Java applications are offered through web browsers as either a Java Webstart application (which do not interact with the browser once they are launched) or as a Java Applet (which might interact with the browser). This change does not affect Web Start applications, it only impacts Java Applets.

Developers and System administrators looking for alternative ways to support Firefox users should see this blog regarding Launching Web Start applications.

I need to use MinimWatch/Server to edit the rules for the display of tracks on the Naim app, which I used to do via the menus in MinimWatch. See the attached pictures for the display rules which I kept as pictures from the past, just to be sure . Is there any other way to edit these display rules?

Grateful if you could help me!
