I tried to config OpenVPN client for Express VPN and it does not connect for all servers
I am getting the following error
WARNING: --keysize is DEPRECATED and will be removed in OpenVPN 2.6

neither stdin nor stderr are a tty device and you have neither a controlling tty nor systemd - can’t ask for ‘Enter Auth Username:’. If you used --daemon, you need to use --askpass to make passphrase-protected keys work, and you can not use --auth-nocache.
