    @sankum unless you enable it and provide a certificate, MagicMirror is http only
    your url is https;//

      Thanks Sam. I changed it to http:// and even tried local IP address instead of localhost and the result is the same. Still the same error, and does not load.?

        @sankum if you change to a file url in a browser

        file:///home/userid/MagicMirror/modules/....
        

        does the file load? this proves the file path and character case
        remember linux is case sensitive

        then replace in front of /modules
        with

        http://localhost:8080

          Hi Sam,
          file:/home/sankum/… loads with 1 slash in the browser. But nhttp://localhost:8080/modules/… does not, same errors as before?

              Sam, MagicMirror is configured to port 8080. nhtp was a typo. It is http://…
              As I said the file path and name are correct as I can read it in browser using file:/… (single slash). So not quite sure what is going on?

                    @sankum I used the sample from the readme

                    {
                      "items": [
                        {
                          "name": "Watt",
                          "value": "270 Watt"
                        },
                        {
                          "name": "Today",
                          "value": "5.85 kWh"
                        },
                        {
                          "name": "ThisWeek",
                          "value": "5.83 kWh"
                        },
                        {
                          "name": "ThisMonth",
                          "value": "12.8 kWh"
                        },
                        {
                          "name": "LastMonth",
                          "value": "246.75 kWh"
                        }
                      ]
                    }
                    

                    in the module folder
                    and this config (from the readme)

                    {
                      module: 'MMM-JsonTable',
                      position: 'top_right',
                      classes:'page1',
                      header: 'HouseDB Sevensegment',
                      config: {
                        url: 'http://localhost:8090/modules/MMM-JsonTable/foobar.json', // Required
                        arrayName: 'items' // Required---
                      }
                    }  
                    

                    and it displayed as expected

                      Thanks Sam.
                      So do I need port 8090 based on your config?. In my config port definition I have:
                      port: “8080”,

                      Other than that I don’t see any difference. Do I need to change router setting? Any missing package you think? Thanks.
