"Error writing to SSL connection" on FreeBSD

[lessless]

Hi,

I'm using openfortivpn 1.21.0 on FreeBSD:14:amd64 and it dies after a couple of minutes with the following error:

I tried suggested ppp.conf doas openfortivpn -c /usr/local/etc/openfortivpn/flattire --ppp-system flattire-vpn -v -v

flattire-client:
 set dial
 set speed 38400
 set mru 1354
 set login
 set timeout 0
 disable deflate pred1
 deny deflate pred1

but with no luck
