We are trying to implement DUO for our SSL VPN using Fortinet Firewall/Routers v 6.2.9 and we consistently receive the following error:

Has anyone run across this before and know what is causing the issue? I’m not finding much using google.

Take a look at How do I resolve “Certificate verification failed” and “SSL handshake failure” errors when using the Duo Authentication Proxy?.
If you work through this article and still can’t resolve the issue, contact Duo Support.
