Compression block connection

Post by flarup » Sun Apr 02, 2023 10:23 am

I have a self hosted openvpn connection which works fine on my Linux and Android, now I suddenly needs it on Windows-10

I installed openvpn and loaded the ovpn file, and then I got the log below

I looks like compression is being used, but compression should not be used in version 6.1+

Code: Select all

2023-04-02 12:06:07 Note: --cipher is not set. OpenVPN versions before 2.5 defaulted to BF-CBC as fallback when cipher negotiation failed in this case. If you need this fallback please add '--data-ciphers-fallback BF-CBC' to your configuration and/or add BF-CBC to --data-ciphers.
