Create a simple VAST XML

I'm looking for someone to create a VAST XML file for me to host on my server, it just needs to contain a single video and URL. I've created VAST code which works on Google's developers console, but when I upload it to XML onto my server it doesn't work.

Code:

<VAST version="2.0">
<Ad id="static">
<InLine>
<AdSystem>Pre Roll</AdSystem>
<AdTitle>Pre Roll</AdTitle>
<Creatives>
<Creative>
<Linear>
<Duration>00:00:03</Duration>
<VideoClicks>
<ClickThrough>https://watcha.movie</ClickThrough>
<ClickTracking>https://bit.ly/123456</ClickTracking>
</VideoClicks>
<MediaFiles>
<MediaFile type="video/mp4" bitrate="300" width="1920" height="1080">
https://watcha.movie/intro.mp4
</MediaFile>
</MediaFiles>
<Icons>
<Icon program="AdChoices" height="16" width="16" xPosition="right" yPosition="top">
<StaticResource creativeType="image/png">

</VAST>
