Important note about SSL VPN compatibility for 20.0 MR1 with EoL SFOS versions and UTM9 OS. Learn more in the release notes.
Since Sophos XG is depended on OpenVPN for many clients, we only use it for all:

Since openvpn-connect-3.4.0.3121_signed or 3.4, i get the error "Unsported Options" and i cant connect.
So i removed after looking at the log, the options "route delay 4", what does it do? Is it important?
I tried to reach out for the support, but you get the classic "not our product, not our problem" answer. Maybe someone can it explain it me, but is this a bug from openvpn or does sophos not support the new configuration rules for newer version?
And is there a permanent fix, which does not get whiped after a update?
