To troubleshoot a DNS error, start by reviewing the error details for each server node in the DNS tree. If DNS errors are frequent, consider setting up a separate DNS task with “Verify Response On” set to “First Responding” and monitor the domain’s resolution regularly.
Also, you should investigate areas like network devices, browsers, DNS records, your service provider, and potential latency issues. It’s helpful to have a troubleshooting checklist, starting with the easiest items to review, like network devices, before moving on to more complex issues, such as misconfigured DNS records or latency problems.
