Install Tizen .wgt using URL Launcher

I have developed a tizen web app and I have installed it to signage using device manager. Now I want to install the same app using URL Lancher. I have taken wgt using Tizen: Build Tizen Project .
It generated wgt file in debug\tv-samsung-8.0 folder. I have taken it and created sssp_config.xml and I have place the wgt and sssp_config in in aws s3 in a folder tizen
I entered the url till tizen in url launcher and signage showing “unable to download the app. Please try again later”.

sssp_config.xml

<sssp_config>
<app id="xtuzY.myPlayer">
<package_url>https://<my hosted url>/tizen/myPlayer.wgt</package_url>
<main>index.html</main>
<auto_start>true</auto_start>
<encryption>false</encryption>
<resolution width="1920" height="1080"/>

</app>
</sssp_config>
