I do not agree with you. I am running my own VPN Server outside of Mainland China and thanks to obfuscation my VPN is working quite well and its very reliable.

Have you tried iVPN with obfsproxy? Or AirVPN with stunnel? Or VyperVPN? Just curious.

Are you by chance aware of any simple tutorial for ShadowSocks? Last time I looked at the website it didn't seem straightforward to set up (particularly for non-techies).

Also, one needs an exit server, or not?

SoftEther VPN (Open Source) works over HTTPS and UDP, that might work for you. https://www.softether.org/
