SoftEther VPN client stuck on “Verifying Certificate” (Error Code 2)
Posted: Sat Feb 07, 2026 10:18 am
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
