I can't reach some websites with VPN+Tor

I have not had the problem with github but a free VPN site.
I am using Windows 10 with desktop 11.06 of Tor. What always happens is while connecting to Free OpenVPN USA Servers - VPN Jantit to get a free account there is a CAPTCHA that doesn’t appear while I use Tor. I also got an error which I enclosed.
