The last solution that you can try is to block the IP addresses in the ConfigServer tab. Having said that, if you don’t intend on using the open DNS server, it’s suggested to set up restrictions on DNS configuration, which means only authorized hosts can leverage the server for responding to the queries.

If modifying the settings doesn’t help you out, you could try checking the DNS forwarder. In addition, it is suggested that you change the name configurations as well. So, the first solution is to open the internet settings, forget the internet network, and manually modify the connection. Honestly, the connection drops, but it doesn’t cut out the connection.
