Why is the openvpn client not reading the config file normally from the server?

Question

linux

Hello.
1) I raised openvpn on a Dutch server (ubuntu), generated a config file.
2) I uploaded the config file to my home server (Debian GNU/Linux 8 (jessie).
3) I start the VPN connection openvpn --config /root/box.ovpn and get an error

Options error: Unrecognized option or missing parameter(s) in /root/box.ovpn:17: tls-crypt (2.3.4)
Use --help for more information.

Line 17 is the second line of the certificate, it turns out that openvpn does not read the line with the certificate correctly, although all the tags are written correctly

Answer 1

The error is not where you indicated, but in the tls-crypt tag.
What version of openvpn is on the client? tls-crypt was only introduced in version 2.4
Use tls-auth.

Answer 2

Purely theoretically: several lines with a certificate can be considered as one. So do head -n 17 /root/box.ovpn - what gives?
