SoftEther VPN User Forum

After reinstallation of softether I wanted to use the same registered hostname but I can't because it shows the message that the hostname already exists. So perhaps I forgot to save the dns key from the server config.file. Is there a way to delete a registered hostname to reuse it again (delete abc.softether.net and after that reassign abc.softether.net). Or can one get the forgotten dns key back?

I'd be interested in knowing this as well since I accidentally smoked my config during an upgrade.

When the host name has changed since the last time VPN server was started, the VPN server regards the configuration file as being copied and regenerates the DDNS name.
To restore the DDNS name, copy the DDNS Key field from the old configuration file.

Same case for me.
