It's impossible to know wtf is going on. The videos on NHL.com never play when I click them. Not on my phone or computer. Just the spinning wheel of death.
But last night clicking the Sabres link forwarded me to the NHL app where it worked on my phone but not on my computer. And get this, when I tried to use Chromecast to put the game on my TV, it caused the feed to stop!
So apparently they only allowed viewing on phones last night away from Buffalo. Again, I'm spitballing here.
What VPN and set to where? I have Mozilla VPN and it made no difference.
