Because SoftEther VPN is overly strong tool to build a VPN tunnel, some censorship governments want to block your access to the source code of SoftEther VPN, by abusing their censorship firewalls.

To circumvent your censor's unjust restriction, SoftEther VPN Project distributes the up-to-date source-code on all the following open-source repositories:

$ git clone
$ git clone

We hope that you can reach one of the above URLs at least!
