DNS_PROBE_FINISHED_NXDOMAIN – Internet address not found

The domain name could not be resolved; Typos or DNS problems are possible.

Do not factory-reset a router speculatively or indiscriminately disable Wi-Fi security or a firewall. Get permission before changing someone else’s network.

Check the address character by character and test two other websites.
Test the same address on a second device on the same WiFi. If only one side is affected, the problem may lie with the provider.
Restart the browser. If there are multiple affected sites, clear DNS cache and check router status; Do not change company DNS yourself.

Test after each step and stop when the issue is solved. Checkmarks are not permanently saved.
