FortiClient VPN: Can't Connect

Owner Marcus Ortega · updated 2026-07-14

Stuck at 98% or 'credential or SSL VPN configuration is wrong': check the MFA push, hotel captive portal, and client version 7.4+. Hotel and airport Wi-Fi often block the VPN port; use a phone hotspot to test.

  1. Open a browser first and accept any hotel or airport captive portal.
  2. Confirm the MFA prompt on your phone. Stuck at 98% usually means the MFA push timed out.
  3. Check the client version (Help > About). Anything below 7.4 must be updated by IT.
  4. If hotel Wi-Fi blocks the VPN, connect through a phone hotspot to confirm.
  5. Still failing: send IT a screenshot of the error and the time it happened. IT checks the firewall logs.
