The Ensighten Bootstrap can be blocked from some sites or tools either by default, client, or developer tools.
These blocks are often manifested in following ways:
- Some calls are redirected and cause an HTTP Error 307 Multiple request message instead of HTTP Error 400 Bad request.
You will notice that the Bootstrap call never reached Ensighten because there are no
serverComponentcalls on the page.
- By default, most ad blockers whitelist the Ensighten Bootstrap (nexus.ensighten.com).
- Some ad blockers use different blacklists based on geographical location and as a result block Ensighten.
Known apps that might block or redirect Ensighten:
- Adblock Fast (Mobile and Chrome)
- Crystal (iOS and Android)
- Purify (iOS)
- F-Secure’s Freedome (Windows and Mac)
- Firefox (Private Window Mode)
- Disable "Tracking Protection"
When you open a new Private Window
use the toggle to disable
Or click the shield icon on top right corner
and select "Disable protection for this session"
WORKAROUND: Some tools such as Ghostery and Adblocker allow customers to manually select page calls and disable them. It is best to help customers understand these tools and the benefits they provide.
- Ad blocking: a technology that prevents or filters content from loading in a browser. Ad blocking is used to provide pages that load faster and to improve security. Ad blocking tools capture the calls on a page and then compares the call with either a blacklist or whitelist such as Easylist.
- Blacklist: a list of items, such as user names or IP addresses used to control access to systems or protocols. Blacklist controlled access allows everything except those on this list. For example, a firewall might use a blacklist to deny access to individual users or systems located in certain regions. Spam filters often include blacklists to reject certain email addresses and message content.
- Whitelist: a list of items, such as user names or IP addresses used to control access to systems or protocols. Whitelist controlled access only allows those on the list. For example, some firewalls are configured with a whitelist to only allow specific IP address access. Email systems sometimes only accept messages from addresses on a whitelist.
