Wish I could help, but as someone with a paid version of Nord, I get that 'VPN detected' error message with all attempts to get into any Olympic site...except for the German site shown on soyouwanttowatchfs.com. Will your VPN link to Germany? I understand that Nord is among many VPNs which are forbidding getting into Olympic events online. For some reason that country does allow me in with the VPN.
One odd thing is, I tried to 'go to Canada' for CBC sports, but doing so, one must click on Videos and that takes you to the GEM signup site. I did get registered in there with the help of a poster giving us a list of Canadian zip codes, and I resgistered using my Google account info. I got in the first day, during curling, but later it wouldn't even allow me in! Also, my PC started going nuts when I went in to YouTube. I learned that the GEM account was linked to YouTube, so I unlinked it to get my PC to settle down.
I'd like to know if there is ANY country my Nord could use for the Olympic YouTube channel. I think there is not, for reasons given above. I do wish you luck on finding something. Can you try the live.qq.com/10012776 link? If you can get in, it does work. If too busy, it just 'stutters' and is unwatchable though.
