Update SSL VPN to newest OpenVPN version.
MacOS users with the newest version of Tunnelblick are starting to experience compatibility issues with the current OpenVPN version used by SSL VPN.

I still have problems with Tunnelblick 3.8.1
If I change to Default 2.3.18 - OpenSSL v1.0.2m, still the same issue. Why took that so long to fix it? At the moment the only way is to run a virutal Windows with the native VPN-Client..... :(

I contacted Sophos support and they sent me a KB article that resolved this issue for me. I had a user getting a message saying:
"Warning: This VPN may not connect in the future"
"'comp-lzo' was deprecated in OpenVPN 2.4 and removed in OpenVPN 2.5"
Follow the steps here and it should resolve the problem:

There are more reasons to do this. I created another "idea" to do this simply because the current windows client version that is distributed is over four years old and flagged as INSECURE by my software inventory tool.
So please Sophos, do something about this.
Yep, we are seeing this issue too. Users get this message on first connect:
"Warning: This VPN may not connect in the future
'comp-lzo' was deprecated in OpenVPN 2.4 and removed in OpenVPN 2.5"
Can we have the options to choose the profile config that the users download?
