I am familiar with VictronConnect on bluetooth and Android - no problems there.
Today I purchased MK3-USB interface, installed VictronConnect 5.42 on laptop and desktop PCs, tried 2 brand new LAN cables to connect to new Multiplus 12|500|200 (which is powered on). VictronConnect simply reports "No devices found"
Have tried different computers and cables, reinstalled VictronConnect, turned firewall off, run as administrator. But result always the same, after a few seconds of searching: No devices found
What else can I try?
