First, below is the content of the configuration file of the client OpenVPN before fixing the error. For example, file name client.ovpn.

remote 11194
ca "C:\Program Files\OpenVPN\config\vpnca.crt"
tls-auth "C:\Program Files\OpenVPN\config\vpn.tlsauth" 1
auth SHA256
comp-lzo yes
dev tap
proto tcp
remote-cert-tls server
remote-cert-eku "TLS Web Server Authentication"
cipher AES-256-CBC
script-security 2

And I added the following lines to the bottom of the OpenVPN configuration file on the client.

tap-sleep 3
verb 4
route-delay 1 3
route-method exe
ip-win32 netsh

After adding the above lines at the end of the file client.ovpn, save the file. I restart OpenVPN on the client again and it connects successfully.
