Domain Configuration Errors

Overview

Domain configuration errors occur when DNS records do not correctly map a domain to the hosting environment responsible for serving the website. DNS records determine where browsers and crawlers should send requests when resolving a domain name. Incorrect configuration prevents the domain from reaching the correct server.

Common Causes

  • incorrect A record pointing to the wrong server IP address
  • conflicting A and CNAME records defined for the same hostname
  • missing records for the www subdomain
  • DNS zone configured on one provider while nameservers point to another
  • DNS records left over from a previous hosting provider

How the Problem Appears

  • domain resolving to a parked page or default hosting page
  • website loading from an outdated server after migration
  • intermittent site availability depending on DNS resolver cache
  • site accessible via server IP but not through the domain name

How It Is Diagnosed

  • querying DNS records using dig domain.com A
  • verifying CNAME records for the www subdomain
  • checking authoritative nameservers using dig NS domain.com
  • comparing DNS records in the provider dashboard with expected server values
  • tracing DNS resolution with dig +trace

Typical Fix

  • update A records to the correct hosting server IP address
  • remove conflicting CNAME or legacy DNS records
  • create consistent records for root domain and www hostname
  • ensure nameservers match the DNS provider hosting the zone
  • allow time for resolver caches to expire after updates
