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
- Magento Commerce Cloud, all supported versions.
Cache warmup failing.
Steps to reproduce:
Start cache warm up operations.
Pages or whole site loads.
The site is unavailable or the response time is too high. ERROR: Warming up failed: <website link>.
Cache warmup 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 warmup cannot occur in this scenario and access control has to be disabled.
