Sophos Connect 2.3 with disabled IPv6 component

Quallensaft

- upgraded our Windows Connect Clients from 2.2.9 to 2.3
- when now connecting with SSL VPN:

The client is connected (all is working) but the state in Sophos Connect will not switch to connected and stays in "is connecting"... -> not possible to disconnect anymore.

Client Log:

    Can you share your SSLVPN profile in SFOS?

    Those object in network, could you give us an overview about those elements. It looks like, some of those routes are off for Connect. 
    Could you give us also the log of a successful 2.2 connect client?

    - just my internal /24 remote networks that are permitted (no changes made since upgrade)
    - with 2.29 same config, same client, same local network -> working -> LOG:

    Can you raise a support case as well and post the ID here?
    Those errors seems to be new in OpenVPN: https://github.com/angristan/openvpn-install/issues/1193
