SSL WebPortal Mode | Login Failure

[MaDe]

Good day,

I am new to FortiGate and having some trouble to setup the SSL portal. 

First I used FW 6.2.7 setting up the SSL portal with  http://docs.fortinet.com/document/fortigate/6.2.0/azure-cookbook/584456/configuring-saml-sso-login-f.... 

This works perfect but I had some trouble to open external URLs from the SSL portal.

I opened a ticket and support confirmed there is bug in FW 6.2.7 and I can go to FW 6.4.5. Ok so I updated to FW 6.4.5. But now SSL Portal is not working anymore. I get a <ERR_EMPTY_RESPONSE> from my browser. I tried to debug the login with <diagnose debug application sslvpn -1> and saw this error: 

262:root:6]rmt_web_auth_info_parser_common:460 no session id in auth info [262:root:6]rmt_web_get_access_cache:797 invalid cache, ret=4103

But I don't what it means and how I should proceed. Has anyone had a error like this before and can give me some advice.

Many thanks,

MaDe

Do you also have the problem that when you have authenticated yourself and you start an AppProxy application in Azure via shortcut, for example, you have to authenticate yourself again?

Not tried that I'm afraid.
