For Workers & Pages, what is the name of the domain?
What is the issue or error you’re encountering
We are experiencing a persistent 526 status code when a Cloudflare Worker attempts to fetch data from another Cloudflare-hosted domain: https://www.boxhero.io/.
What steps have you taken to resolve the issue?
This Worker had been working fine previously, and we have not made any changes to our code when the error suddenly started occurring.
We verified the SSL certificate and everything appears to be valid.
When we run the same fetch request locally or create a new Worker with the same code, the request completes successfully without errors.
The error only occurs in the existing Worker, and it continues to happen even after we re-deploy it without any changes.
What are the steps to reproduce the issue?
The issue is difficult to reliably reproduce because creating a new Worker with the same fetch logic does not result in any error — it works as expected.
