      @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

            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.

                                    Sam,

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