This medium-severity issue affects the network adapter. A common browser error code displaying when the web browser cannot resolve a website's domain name because the DNS server reports that the domain name does not exist (Non-Existent Domain). It's most often caused by corrupt local DNS resolver cache, incorrect network DNS servers and VPN/firewall blocking DNS requests. The steps below are ordered to resolve this efficiently.
Common Causes
- Corrupt local DNS resolver cache
- Incorrect network DNS servers
- VPN/firewall blocking DNS requests
Step-by-Step Fix Guide
-
1
Flush DNS resolver cache
Flushing the DNS cache removes bad hostname-to-IP records stored locally.
-
2
Change DNS servers to Google DNS (8.8.8.8) or Cloudflare DNS (1.1.1.1)
Changing to reliable public servers bypasses failures in your ISP's custom DNS nameservers.

Try "Restart the router" next if the issue persists — it addresses a secondary cause.
