Toolkit not updating application log & lighting events.

Hi everyone,

I'm hoping someone can point me in the right direction because I've reached the point where I think I'm missing something fundamental.

I have a moderate C-Bus installation with:
CNI MkII
Wiser2
OpenHAB/Home Assistant
pktechnology C-Gate docker (currently 3.7.1)

This setup has worked previously however recently I have noticed that Toolkit's Application Log and the lighting group levels have stopped updating, although I still get measurement data from the CMU appearing in the application log.

I was running Toolkit 1.17.7 and C-Gate 3.3.4, thinking it may have been a compatibility/software issue, I have upgraded to Toolkit 1.19.4 and C-Gate 3.7.1 but the behavior is exactly the same.

For example, monitoring the event interface (TCP 20025) shows:

lighting on Matt Room Fluro #sourceunit=54
lighting off Matt Room Fluro #sourceunit=54

and measurement events such as:

measurement data //4BLACKWD/254/228/10/1 ...
continues to stream normally.

The strange part is that Toolkit only appears to display the measurement events. Lighting group changes never appear in the Application Log.

Under Toolkit preferences both Live Levels and Application Log are ticked

Any ideas would be greatly appreciated because I'm running out of things to test.

Thanks!
