Are you talking about the VPNGate servers? Most of these servers don't work well anyway. Or did you set up your own server?

My Korean SoftEther server still runs great.

Which port are you connecting to and are you using UDP? I would stick to Port 443 TCP only since it is SSL traffic that should be undetectable by the GFW.

SoftEther for the time being seems to be one of the few remaining protocols that passes the GFW without disruption.

In China, the SoftEther VPN Client has been unable to use it as if the UDP TCP protocol included many ports that were shielded by telecommunications

You can set the client to use any TCP port. I would recommend port 443 which is commonly used for https. You can also use port 80 which is the common http port but some servers may have this port blocked. You will need to use TCP. Using UDP acceleration is an option. So unless the SoftEther server IP address is blocked in theory you should be good to go.

My SoftEther server was blocked on 3 different ports that I was using. Here is what is really weird:

1) The blockage is only on China Telecom (I tested on 2 residential connections) but it is not blocked on another China Telecom account (which was also signed up as a personal account but is in an area 3 km from my home).

2) Another port is not blocked so the blockage is port specific.

3) It is not blocked on China Mobile nor China Unicom.

So here you have it: the blockage is not by the "GFW" but by the specific ISP and in fact regional. Choosing another port solves the issue.

You may recall that there was a news article stating that the government is forcing ISPs to block VPNs so the block is ISP specific. What is also strange is that I have practically never connected to my VPN server via the China Telecom residential connections.

Can you show me where the UDP acceleration option can be turned on or off?
