### Streamlink version

streamlink 6.1.0

### Description

Hi team. I was able to get stream url from following page successfully for past weeks. Two days ago, I found streamlink isn't able to retrieve the steam url:

web page: https://www.media.gov.kw/LiveTV.aspx?PanChannel=KTV1
This is the official website of Kuwait for their national channels.

I tried 3 different machines on different operating systems where streamlink was working successfully and retrieving the stream url for this website. All recently failed with same message (No playable streams...etc.)
