We are parsing the HTML and trying to download the URL and content of the page can change and can cause this issue, did a google search to find a direct API, but looks like this is the only best way to get the data,

👍 @AltamashShaikh was just wondering why it worked before and now not anymore and if we can make the solution more stable in case they change their HTML again tomorrow back to what is was for example. Not too important maybe, was just checking if we know why it broke.

@tsteur I didn't see an exact reason for the change. As Altamash mentioned, it looks like the content periodically changes and we have had to make other adjustments in the past. I'm not really sure if there's a good way to make it less fragile when they change things on us. I added an integration test that will hopefully help alert us better.

Thanks @snake14 👍
