The net::ERR_NAME_NOT_RESOLVED error may suggest intermittent connectivity issues, such as DNS resolution failures. This may happen infrequently if your network has temporary hiccups or DNS servers are overloaded.
To troubleshoot, check if the domain/IP can be accessed consistently, verify DNS settings, and try using a public DNS server like Google (8.8.8.8) or Cloudflare (1.1.1.1).
In contrast, the 404 Not Found error indicates that the specific resource or URL being called does not exist on the server, making it easily reproducible.
Infrequent occurrence of ERR_NAME_NOT_RESOLVED could also arise from caching issues—clearing your browser's cache or resetting your network settings may help mitigate this.
