Error message Description
The app often redirected the scanner to an authentication page If you're using Google authentication, the scanner detects auth redirects. Most likely the credentials you're using to scan the site are invalid. To check this, start a Chrome incognito session and try to log in with the test credentials on your application.
The app produced a high number of errors during this scan Web Security Scanner found that a high percentage of requests resulted in 4xx or 5xx HTTP responses. Verify your scanning credentials and the target URL. If the problem continues to occur, please file a bug.
The scan found a small number of results during crawling Web Security Scanner didn't find many pages to test. This is expected for sites that don't often change the URL and sites that have application features behind multi-step navigation bars. Try adding more seed URLs, like the URL for each feature that a navigation bar leads to.
The scan found too many URLs while crawling results and has not tested all of them. This problem can appear if your app has many URLs that lead to the same template. In this case, file a feature request and the team might be able to tune the duplicate-page logic for you.
The scan hit an internal exception This message can indicate one or more internal errors. If you get this message, please send feedback about the specific scan.
The scan timed out while crawling the app

There is a time limit for each stage of the crawler.

  • If you have a very large site, then this can be expected. File a feature request, and the team can manually increase your crawl timeout.
  • If you have a small site, then something might have gone wrong with the crawler. File a bug with your scan details and the team will investigate.
The scan triggered a DDOS protection mechanism and has been stopped This is caused by too many queries, too fast. Try reducing the Queries Per Second (QPS).

Fixing issues

If Web Security Scanner reports an issue, you need to disable browser cross-site scripting (XSS) protection and then verify the location. For more information, see Verify the issue.
