Why has my scan stalled?
------------------------

Some reasons that the scan may have stalled include:

*   The initial scan sometimes takes much longer than subsequent scans.
*   If this is not the first scan, the problem is in most cases due to post-processing. Rescan the website manually. If the problem persists, contact our [support team](mailto:support@monsido.com).
*   If this is the first scan after recently adding a large amount of content to your website, this could cause the scan to stall.
*   If the page is protected or requires a login, the scan may stall if the login has not been provided in the Web Governance setup. See [Scan Password Protected and Internal Only Pages](https://docs.acquia.com/acquia-optimize/docs/admin/configure-scans/scan-setup-advanced?cid=59ee8) for instructions on how to set this up.
*   For pages that require a login, check that the submit button (submit selector field) has a name or ID value. See [Scan Password Protected and Internal Only Pages](https://docs.acquia.com/acquia-optimize/docs/admin/configure-scans/scan-setup-advanced?cid=59ee8) for instructions.
*   If there are no obvious errors, try to navigate to the site in your browser and see if there is a pop-up that is possibly blocking any additional action on the page.

If a scan stops because the amount of data is extremely large, try to limit the number of pages scanned with path constraints or link exclusions. See the user guide article::

*   [Path Constraints and Link Exclusions](https://docs.acquia.com/acquia-optimize/docs/admin/configure-scans/path-constraints-and-link-exclusions?cid=a70ab)
