I have had some sources block VPN whereby nothing opens. I changed VPN Server to a different location and streams opened.
Livestreams sometimes block VPN IP'S or throttle connection. Maybe try changing server locations.
I use IP Vanish and a server in my country. I have had streams open using my ip without VPN. I then turn on VPN Server in my country and nothing opens. I switch to a VPN in Dallas USA and the streams open. So it's not geo blocking.
I realised the same problems with ipvanish. I turned vpn off as well. It worked straight away. So I have to change the server as well.
