FortiClient SSL VPN Error: Unable to establish the VPN connection. The VPN server may be unreachable
Hi,
I started having issue recently with FortiClient (Windows) from versions 7.0.7 to v 7.2.1.0779.
All my FortiClient are connected to Licensed EMS server (on-prem) and SAML enabled with Azure IdP for VPN login.
SSL VPN fails at 70% or sometimes at 98% with the error: Unable to establish the VPN connection. The VPN server may be unreachable. (-6007)
I have reinstalled different client versions but still same error. Some community posts suggest internet issues but i don't think it is. On the same network, FortiClient v7.2.0.0101 (Android) SSL VPN works with SAML enabled and Windows Add vpn option with FortiClient as provider works well too (Ofcourse no SAML for this)
I have checked logs in Fortinet folder and see following errors under:
