Minim watch not working

[Aitch]

Hi, My install of Minimwatch has stopped working. It will not find or control MinimServer. I have now tried updating to Minimsever2 and minimwatch2 but with the same behaviour. I notice from the log that minmwatch is looking for 192.168.1.175:9791. (I was expecting :9790 but don't really know what this means).
I am using a Synology DS213J NAS, a TP Link Archer VR900 router, and I have tried disabling the windows firewall. Minimserver seems to work and I can trigger a rescan from its own web page but Minimwatch seems rather isolated.
Can you offer any sugggestions to resolve this please. I attach a screenshot of the Minimwatch log files.
