SoftEther VPN client stuck on “Verifying Certificate” (Error Code 2)

Hello everyone,

I’m having an issue connecting to a SoftEther VPN server. When I try to connect, the process gets stuck at “Verifying Certificate” and after some time it fails with this error

I am located in Iran, and currently the internet here is under very heavy filtering, DPI, and protocol-level restrictions. Many VPN protocols and encrypted handshakes are actively interfered with or blocked, which may be related to this issue

Yes, they are blocking VPNs. Get your server's certificate and on SE client enable "Always Verify Server Certificate" and "Specify Individual Cert".

How's it now?
