Best answer by Flood and Flood's wife
Until the end of last season (early May 2019) I was able to listen to the live matches and watch the latest videos but since the start of the new season (early August 2019) I have been unable to do either.
Since May 2019 there have been a couple of Cumulative Updates to the Windows 10 system which is on my PC.
KIS has been on my PC for several years.
I am not aware of any network changes or router upgrade and I have been with the same ISP for several years. I do not believe there have been any software changes
