**Issue**
---------

When running Content Hub's import queue I am seeing errors about missing headers:

`[error] Response is missing required` X-Server-Authorization-HMAC-SHA256 `header. [XX.XX sec, YY.YY MB]`

**Resolution**
--------------

There are a couple ways to bypass/fix this issue:

*   If possible, you could add permission for these requests in your firewall to allow your headers past.
*   You could also try changing your webhook URLs to the default acquia-sites url to bypass that layer of routing.

If both methods fail and you’re not able to resolve it quickly, contact Acquia Support.

**Cause**
---------

Generally this error is caused when an application's webhooks are set to a domain that is behind something like a WAF (like Acquia Edge). These requests likely need to bypass that layer or get added to its ACL.
