The following are the possible reasons for a scan to stall:
If this is not the first scan, the problem is typically due to post-processing. In such cases, rescan the website manually.
If the problem persists, select Contact support in the Help menu to start a chat, or email Acquia Support.
If the page is protected or requires a login, the scan may stall if the login is not provided in the Web Governance setup.
For instructions on how to set this up, visit Configure the scan for password-protected and internal pages.
For pages that require a login, check that the Submit button has a name or ID value.
For instructions, visit Configure the scan for password-protected and internal pages.
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.
For more information, visit Scan exclusions.
