    Hi, if i search for OpenVPN at google play, it doesn't show any results. I need it, so i've downloaded from ApkMirror, install without problems, import the .ovpn file and ... doesn't connect.
    Android version 9
    Oxigen OS 9.5.11.GM21AA

    Hi everyone,

    I'm having issues on OpenVPN as well since I updated to Oxygen OS 9.5.11.GM21BA (I already had the application installed before updating and everything was fine before that).

    The tunnel is up but there is no connectivity at all.

    Inside the application I see:

    14:09:05.595 -- Connected via tun
    14:09:05.595 -- EVENT: CONNECTED info='xx:xx:xx:xx:1195 (xx:xx:xx:xx) via /UDPv4 on tun/ gw=[]'
    14:09:14.645 -- TUN write exception: write_some: Invalid argument
    14:09:24.766 -- TUN write exception: write_some: Invalid argument

    I will transfer this to openvpn android[at]openvpn[dot]net in case it's their concern.


    EDIT: After getting in touch with the lead dev, my issue was caused by the setting of OpenVPN Connect 3.0.6:
    Compression is now Disabled by default in this version (and it does override the "compress lzo" line of my .ovpn file). If your were using compression, you can force it, but you should consider updating your server config to disable it as it is not considered secure (anymore).
