How to make DNS in Win10 work fine with OpenVPN?

Question

openvpn

Introductory:
* OpenVPN server, in whose performance there is no doubt
* several .ovpn files with identical configurations, except for keys
* full system performance on Ubuntu / Android
* DNS errors in Windows: OpenVPN establishes a connection, you can ping something by IP, but DNS does not work at all
The configuration looks like this:

client
dev tun
proto udp
sndbuf 0
rcvbuf 0
remote SOMEIP 80
resolv-retry infinite
nobind
persist-key
persist-tun
remote-cert-tls server
auth SHA512
cipher AES-256-CBC
setenv opt block-outside-dns
key-direction 1
verb 3
<ca>
-----BEGIN CERTIFICATE-----
SOMECERT
-----END CERTIFICATE-----
</ca>
<cert>
-----BEGIN CERTIFICATE-----
SOMECERT
-----END CERTIFICATE-----
</cert>
<key>
-----BEGIN PRIVATE KEY-----
SOMEKEY
-----END PRIVATE KEY-----
</key>
<tls-auth>
-----BEGIN OpenVPN Static key V1-----
SOMELEY
-----END OpenVPN Static key V1-----
</tls-auth>

What am I doing wrong and what logs can be useful in this situation? The OpenVPN client itself does not report errors.
