minimwatch unable to create tray icon

What version of Java do you have installed? If it is the headless version (provided by default on some Linux systems), you will get this message. You need to install the full version of Java including graphical user interface support.

For details of how to install the correct version of Java on Raspberry Pi OS, see this section.

Also, you don't need to install MinimWatch as well as MinimServer if you are running MinimServer on the Raspberry Pi only (not on any other devices).
