So, Its been more than two days. I have tried to follow every tutorial to upload the 360 video in my ASP.NET core. Earlier I was trying to mimic the website which I have mentioned in my previous question. Which is not working, so I thought just to download the video from there and try to add it by using simple code:
html>
<head>
<script src="https://aframe.io/releases/1.2.0/aframe.min.js"></script>
</head>
<body>
<a-scene>
<a-assets timeout="30000">
<video id="urbanCity" src="~/video/progressive.mp4" autoplay></video>
</a-assets>
<a-camera>
<a-cursor></a-cursor>
</a-camera>
<a-videosphere src="#urbanCity"></a-videosphere>
</a-scene>
</body>
</html>
This is the screenshot of my console:

On my previous question someone relied that the timeout warning-->core:a-assets:warn Asset loading timed out in 30000 ms but in order to fix it I already added the aframe.js reference in head but no change can be observed.
