Hello,

I'm using SSLVPN and am getting "Bad compression error" as mentioned in below post:

Downgrading OpenVPN client to version 2.3.10 solves this issue.

As discussed with Sophos Escalations Team, raising a request here to upgrade OpenVPN server of Sophos to make it compatible with newer versions of OpenVPN client.

Ubuntu 18.04 onwards ships with newer version of OpenVPN client and its older versions are no longer supported on Ubuntu 18.04 onwards. Hence, it would great if this can be done at the earliest.
