Does this have anything to do with the Helix text editor?

What brand of VPN do you use to bypass it, many of my friends are there quite frequently, none of them have a mainstream solution for it.

Last time I was there, express do not work, and I heard proton also does not work. However, my mobile carrier by default routes all roaming traffic through UK, so that did work.

China blocks most IPs from foreign cloud providers like AWS or Digital Ocean. And if I am not mistaken, they can also block some VPN protocols, but I am not sure which exactly.
