Hello,

Nextdns simply stopped to work here. DNS addresses are not reachable from this network:

inetnum:     189.45.192.0/20

Troubleshooting:

$ sh -c 'sh -c "$(curl -s https://nextdns.io/diag)"'

Welcome to NextDNS network diagnostic tool.

This tool will download a small binary to capture latency and routing information
regarding the connectivity of your network with NextDNS. In order to perform a
traceroute, root permission is required. You may therefore be asked to provide
your password for sudo.

The source code of this tool is available at https://github.com/nextdns/diag
