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

[ramtin]

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
