softether packets not received by server in Iran

[morty]

I live in Iran, I have a Softether server, and it worked very well for 4 months but recently our government blocked Softether packets and I can not connect to the server, I can have an SSL connection with famous sites like Google but TCP connection on port 443 on other machines will block.
I don't understand How they selectively detect Softether VPN packets and they restrict reaching these types of packets from clients to VPN servers.
can you help Iranian people from escaping of these hard censorships?
This problem is for all Iranians who used to use Softether.

With Best Regards

制限を行っている人が、まだ TCP しか検閲の対象としていないのであれば、もしかすると VPN over ICMP モードは、まだ利用できるかも知れません。
