This is the wrong solution for two reasons. 1. Compression has been disabled by default for a good reason - it can be used as an attack vector. 2. Not all clients allow changing these settings - I can’t see any way to change settings in OpenVPN Connect on android for example. What’s the proper fix for this? I can’t see any way to disable compression in the Pritunl UI. ---

There is no option to enable compression, in very old releases there was an option but it is no longer shown and disabled by default. Enabling debugging output in the server settings will show the server configuration in the output when starting. The line `allow-compression no` would indicate it is disabled. Chrome Developer Tools could also be used to view the response from the server page and check the value of `lzo_compression`. ---

Perfect, thank you. `lzo_compression` is set to false so I’m not sure why the Android OpenVPN client is giving me `Transport Error: server pushed compression settings that are not allowed and will result in a non-working connection.` ---

I’ve resolved the problem by selecting “Legacy” for the security configuration in the OpenVPN Connect app. > **[Sophos Firewall: Temporary Fix OpenVPN (3.4.0) No Compression (Android...](https://community.sophos.com/sophos-xg-firewall/f/recommended-reads/143651/sophos-firewall-temporary-fix-openvpn-3-4-0-no-compression-android-devices)** > > Disclaimer: This information is provided as-is for the benefit of the Community.
