      @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.

                          Hi Sam,

                          Never mind!! It is port 8080.
                          I copied the json file you have shown and it worked. So it must be my json file. I will try to figure out what is the difference. Thanks for your help.

                                        Yes, it was the file content. I had copied it from the git example but obviously did something wrong.
