Problem
What does this error code that FortiClient SSLVPN is giving me?
Solution
If FortiClient fails as the following stages, the likely cause is as follows:
- 10% – Local Network/PC issue
- 40% – Application or the Fortigate causing the error, occasionally caused by the local machines/network setup
- 45% – MultiFactor Authentication
- 80% – Username/Password issue
- 98% – corruption of services/often resolved by reinstalling the client on the laptop.
