Can't Get Json to display in ag Grid just says loading

Using various example I have found on the web I pieced together a simple web app. However although AG Grid (the grid I have chosen to display the data works with the data source provided, it does not work with my own data source which was created using a web service written in Go.

Angular code...

ngOnInit() {

     this.rowData = this.http.get('https://api.myjson.com/bins/ly7d1'); 

  }

This works correctly showing the data on the grid. but when i redirect it to me Go generated data using the following...

 ngOnInit() {

     this.rowData = this.http.get('http://localhost:10000/all');

  }

This grid just says loading...

if I test either link in the browser I get the exact same data formatted in the exact same way...

[{"make":"Toyota","model":"Celica","price":35000},{"make":"Ford","model":"Mondeo","price":32000},{"make":"Porsche","model":"Boxter","price":72000},{"make":"Toyota","model":"Celica","price":35000},{"make":"Ford","model":"Mondeo","price":32000},{"make":"Porsche","model":"Boxter","price":72000},{"make":"Toyota","model":"Celica","price":35000},{"make":"Ford","model":"Mondeo","price":32000},{"make":"Porsche","model":"Boxter","price":72000},{"make":"Toyota","model":"Celica","price":35000},{"make":"Ford","model":"Mondeo","price":32000},{"make":"Porsche","model":"Boxter","price":72000}]

Here is the link to the Json:

https://api.myjson.com/bins/ly7d1

I am running both my angular app and the go app on the same machine but there are different services and using different ports...

I could include the Go code but I do not see how relevant it is as the data displays correctly in a browser.

tried to include only the stuff that is relevant but if I have missed something please let me know and I can upload.

Expected Output...

Update I have now tried the following... Completely rewrote the site and service on my Macbook tried using different ports on the server and the client tried running the server on a different machine disabled all firewalls

none of this makes any difference.
