The softether DDNS default domain name is blocked from access

[steven1618]

Hello, when I use softether server, the default dynamic DNS host cannot be accessed, and I learned through inquiry that the local network operator blocked the domain address .softether.net, resulting in my inability to use it. Now I can only replace the default .softether.net dynamic DNS domain name of softether server with another one, I can continue to use softether, how to change?

Can you connect with a direct IP? If not, then "network operator blocked the domain address .softether.net" is not true.

DDNS ==> Dynamic DNS ==> an A record which changes over time

When you run a SE server, if you have access to the Internet, it registers your public IP address as a A record via a sub-domain of "softether.net"
For example vpn12345.softether.net.

So if you ip is 1.2.3.4 and your DDNS is vpn12345.softether.net
if you ping "vpn12345.softether.net" it resolves to your IP "1.2.3.4"

As @solo said, if you cannot connect to your SE server using direct IP (e.g 1.2.3.4) , the DDNS (e.g. vpn12345.softether.net) does not work either.
