#1204 assigned Bug / Defect

OpenVPN Connect 3.0.0 (272) client can't accept server-pushed [compressor]

Reported by: keber Owned by: OpenVPN Inc.
Priority: minor Milestone:
Component: OpenVPN Connect Version:
Severity: Not set (select this one, unless your'e a OpenVPN developer) Keywords:


Using OpenVPN Server from pfsense community edition 2.4.4-release-p3.
Trying out OpenVPN Connect 3.0.0 (272) on Windows 10.
Previously had lzo compression enabled.
Changed this setting to 'Disable Compression, retain compression packet framing [compress]' and enabled Push Compression setting to connecting clients.

OpenVPN GUI v11.9.0.0 on Windows 10 seems to work ok.

OpenVPN Connect 3.0.0. (272) on Windows 10 and OpenVPN Connect 3.0.5 (1819) on Android 9 fails to connect after Sending PUSH_REQUEST to server.

log shows it recieved [compress] option among others. Then the following message:

Client exception in transport_recv: process_server_push_error: Problem accepting server-pushed compressor: option_error: option 'compress' must have at least 2 arguments.
Client terminated, restarting in 2000 ms...

Changed compression setting later to '[Legacy style, comp-lzo no]' seemed to work (it starts the connection) but it doesn't (no traffic).
