Try the Freetube or Grayjay client, they work for me with VPN.

I like how they make up a phony benefit to try to make it seem like you’ll get something out of it.

If you are using a Free VPN, the would be A LOT of users using that server, so it looks like a denial of service attack from the server’s POV.

Even when I used a paid VPN, I still have to try many servers before there is one that works.

When I used ProtonVPN, it was like 50/50 if it worked or not.

When I switched to Mullvad and now to IVPN, who have much less servers to choose from, I have to try like 7 servers before I found a working one, and so far it’s been working fine for like the past week.

Its not a new thing. I’ve noticed it since last year (when I started using VPNs).
