This article provides a solution for when the page cache is warming up and fails with an error:

ERROR: Warming up failed: <website link>

Affected products and versions


Cache warm-up failing.

Steps to reproduce:

Start cache warm-up operations.

Expected result:

Pages or whole site loads.

Actual result:

The site is unavailable or the response time is too high. ERROR: Warming up failed: <website link>


Cache warm-up doesn’t work with HTTP access control enabled.


Ensure that you do not have access control enabled: go to the specific branch/environment and click on the Settings icon, and check the HTTP access control setting - cache warm-up cannot occur in this scenario, and access control has to be disabled.
