I am having difficulties finding the proper URI for MMPM. I have MM running with pm2 command on my PI3 connected through VNC Viewer and Putty.(via help topic elsewhere) I can get into the json file for the variables and make the adjustments. I used MagicMirror as my PROCESS NAME, and its sketchy for me, which name to input here: pm2, PM2, or just MagicMirror, as in the example.
I haven’t been able to access or view the MMPM gui through browsers on the PI or my browser on my Windows Machine. I know you need more info and I’m able to provide it upon request.
