Note the 'failed [sslvpn_login_cert_checked_error]' message.

 

To fix the issue:

 

If connection cannot be established to the FortiGate unit via SSL VPN and the following conditions are true:

  • SSL VPN Status stops at 48%.
  • A pop-up message appears with 'Credential or SSLVPN configuration is wrong (-7200)'.
  • 'diagnose debug application sslvpn -1' debugging shows a 'failed [sslvpn_login_cert_checked_error]' message.

Consider navigating to VPN -> SSL-VPN Settings -> SSL-VPN Settings and disabling Require Client Certificate. Select Apply afterwards to save the changes.

After, try to access the FortiGate unit via SSL VPN again. The issue should be fixed.
