I'm trying to get OpenVPN working with a Chromebook running Chrome OS as a client. When connecting, OpenVPN logs the following:
tls-crypt unwrap error: packet too short
TLS Error: tls-crypt unwrapping failed from [AF_INET]192.168.1.37:37142
The Chromebook on the other end reports no errors, and continues attempting to connect until the timeout occurs.
Attached is my server.conf:
port 1194
proto udp
dev tun
user nobody
group nobody
persist-key
persist-tun
keepalive 10 120
topology subnet
server 10.8.0.0 255.255.255.0

crl-verify crl.pem
ca ca.crt

And this is a rough approximation of the Chromebook's VPN configuration screen:
Service name: hello
Provider type: OpenVPN
Server hostname: <host>
Username: chonk
Password: <omitted>
OTP: <blank>
Server CA certificate: Do not check
User certificate: No user certificate
Below is the output from openvpn --version:

If anyone could give me some pointers that could help me, that would be much appreciated. Thank you.
EDIT: used oconf tags instead of code tags
