If you're in China, you might want to use Shadowsocks. The server is easy to set up on any VPS (no need for TUN/TAP), and there are clients for Android (Shadowsocks), iOS9+ (Potatso), linux and routers.

I've found plain OpenVPN over TCP or UDP stopped working a few years ago (even using remote-random to shuffle ports). PPTP mostly still works.

I haven't used other VPN protocols for a long while, and don't use commercial VPN providers, but occasionally hear from friends that they have temporarily issues (for hours or days, but not weeks).

Thanks, I'll give that a shot next time. I think I tried PPTP when I was there last year without success, but I may be misremembering.
