Cause: Timeout (no headers received)

Edited

Overview

A “Timeout (no headers received)” message typically means the monitoring system was unable to receive a response from the site within the expected time window. In most cases, this is a false alarm and does not indicate an actual outage.


Why This Happens

  • Temporary network latency

  • Monitoring system timing out before the site responds

  • Brief delay while the site is processing a request


Signs You May See

  • Monitoring alert showing “Timeout (no headers received)”

  • Site appears down in monitoring but loads normally in a browser

  • No related errors in site or server logs


How to Resolve

Verify Site Accessibility

  • Open the site in a browser and confirm it loads normally

  • Try loading the site from an incognito window or another network

Check Site Health

  • Confirm the site is running and responsive

  • Verify no updates or maintenance tasks are actively running

Allow a Short Window

  • If the site is loading normally, no action is required

  • Monitoring should auto-resolve once the next check succeeds


When to Contact Support

Reach out to support if:

  • The site does not load in a browser

  • You notice performance issues or repeated alerts
