FortiClient immediateley disconnects 1 second after being connected

[somersst]

If I'm working through a wireless network, I can never connect with my FortiClient. It connects immediateley after being connected. If I do this through Ethernet I don't have any problem.

Hereunder you see a part of the logging I have. I've also included the whole log-file

Did you manage to find the issue ?

I have a client that disconnects after 6 seconds of being connected.

I noticed the same error in your output as my clients. 4/4/2019 2:21:19 PM    Error    VPN    FortiSslvpn: 1004: error: poll_recv_ssl -> SSL_get_error(): 5 4/4/2019 2:21:19 PM    Error    VPN    FortiSslvpn: 1004: error: poll_recv_ssl -> WSAGetLastError():0
