fail to add custom google map to iframe

[yockee]

I made a custom map on google map where you can add KML layer. The map is shared so that anyone with the link can view. I can open the map just fine, no problemo.

Now, i want to incorporate this map into my Portal Site. I have tried several things and still fail:

1. Make the google map as Content. Then I call this Content to Iframe. 

2. Call the address of the map to the Iframe directly.

3. Add the to Application or Map to my portal Site.

Here is the error on iframe:

I can add any other non gis website (just a normal website) fine. It will load straight away.

The only way to incorporate googlemap is via Galery.

How can I be able to add custom google map to iframe directly ? Other normal webpage can be loaded straight away.. 

Thanks

I ask my other colleagues who work on another office with different environment. He experiences exactly the same thing. He can not add a custom google map with KML layer on Iframe. I guess its a problem in arcgis portal itself..
