@Manu85 yes, that means only apps INSIDE the same machine can connect
change
address:"localhost", // means only inside same machine
to
address:"0.0.0.0", // alows any device on any network this machine is connected to to connect
then also the whitelist
comment out the current line
// ipWhitelist: [ 127.....
and add a new line
ipWhitelist:[], // don't filter any connecting client addresses
then restart mm…
if you know the ip address of the pi (and u had to use it for vnc)
then open a tab on you pc browser and do
http://MM_ip_address????:8080
