OpenVPN Client error - Push explicit-exit-notify and block-outside-dns

Installing and Using OpenWrt
1

Hi
I have configured an openvpn client in a nexx wt3020 (runing Luci openwrt).
The openvpn client connects to the openvpn server, but I'm unable to navigate in web.

In log I'm getting the following errors, but in my configuration I didn't config explicit-exit-notify and block-outside-dns:

Mon Sep 30 00:41:38 2019 PUSH: Received control message: 'PUSH_REPLY,dhcp-option DNS 162.252.172.57,dhcp-option DNS 149.154.159.92,redirect-gateway def1,sndbuf 524288,rcvbuf 524288,explicit-exit-notify,block-outside-dns,route-gateway 10.8.8.1,topology subnet,ping 60,ping-restart 180,ifconfig 10.8.8.2 255.255.255.0,peer-id 0'

Mon Sep 30 00:41:38 2019 Options error: Unrecognized option or missing parameter(s) in [PUSH-OPTIONS]:6: explicit-exit-notify (2.3.6)

Mon Sep 30 00:41:38 2019 Options error: Unrecognized option or missing parameter(s) in [PUSH-OPTIONS]:7: block-outside-dns (2.3.6)

Could this be related with the situation of not being able to navigate in web?
How can this be configured?
I'm using OpenVPN 2.3.6 mipsel-openwrt-linux-gnu (Luci openwrt interface)

Best regards

Edit your VPN client/server configuration and remove those options, or add to the client configuration:

pull-filter ignore block-outside-dns
pull-filter ignore explicit-exit-notify

Hi
Many thanks for your help.
I already tried:

pull-filter ignore "block-outside-dns"

but is not recognised by my openvpn version (I think it only supported in OpenVPN >= 2.4.0 acording to this post: https://iflorian.com/openvpn-block-outside-ds/)

How can I do a workaround related with dns? Im using OpenVPN 2.3.6 mipsel-openwrt-linux-gnu (Luci openwrt interface), and I think my router don't support upgrade.

Best regards
