Issue connecting to Fortigate SSL VPN using NM GUI

[bruno bmartins pt]

Hello everyone,

I'm using Ubuntu 18.04 fully updated and currently having issues
connecting to my company's VPN service using NetworkManager GUI. 

If I manually connect from CLI using "sudo openfortivpn
gateway.company.com:443 -u myself company com" everything works as
expected.

Log messages written to /var/log/syslog were pasted here:
https://paste.gnome.org/ph1gz6fvg

It looks like a timeout occurs, but I don't know where I can increase
it.

I believe the problem may be affecting multiple distros, as I could
find this bug report:
https://bugzilla.redhat.com/show_bug.cgi?id=1490874

Sadly, no solution is available.

Can you please take a look?

Thanks!

Kind regards,

Bruno
