Resolver failures

DNS lookup and hostname-resolution issues grouped together

This collection focuses on name-resolution failures where the device, browser, or network cannot translate a hostname into a usable destination path. DNS problems can look like browser failures, router failures, or general internet failures, but the underlying issue is often the same: the resolver path is not returning a healthy result.

By grouping DNS issues into one place, the site makes it easier to identify whether the trouble is in the resolver path, the domain lookup path, or a broader local-network problem that only shows up during hostname access.

How to use this page

Use this collection when websites fail by name, when DNS server messages appear, or when browser/network wording clearly points to lookup failure. If the device is connected but cannot browse and the DNS wording is less specific, compare this collection with the connected-but-no-internet collection.
