Brave.exe is blocked from accessing https://r2---sn-aigzrn7d.googlevideo.com

Hi All
From a few days ago my Brave browser stopped showing some ytube videos and I started getting “brave.exe is blocked from accessing https://r2---sn-aigzrn7d.googlevideo.com” message from my antivirus/firewall.
Is there anything I can do to sort it?
Thanks
