A video platform site doesn't open
Try with VPN
If you already have it - you know what to do. If now we recommend you to install some, e.g. ZenMate. It is free with some speed limitations.

If the video lags - watch a couple of seconds with VPN, then pause, disconnect VPN and continue watching.
Made on
