KB221745: HTML containers in an SSL (HTTPS) environment display blank in MicroStrategy Web

SUMMARY:
This article describes how HTML containers in SSL (HTTPS) environments cannot display unencrypted websites in Strategy 9.4.1 and above.
SYMPTOM:
Users have the option of adding HTML containers to dashboards in Report Services Documents to access websites. HTML containers in SSL environments will not be able to access websites/pages using unencrypted HTTP protocols in Strategy Web 9.4.1. The HTML container will display as a blank square on a user’s dashboard, as shown below:

STEPS TO REPRODUCE:
Follow these steps to reproduce the issue in a Strategy Tutorial Project:

1. Create a document in a HTTPS environment.
2. Insert an HTML container with a website in an HTTP environment.
3. In all modes, a blank space appears in the HTML container.

CAUSE:
This issue is not caused by Strategy Web 9.4.1. The HTML container displays blank because the browser must first warn the users that non-encrypted or non-verified content is being displayed inside an encrypted or trusted web site before displaying the content. It is up to the user to decide whether they want to display the unsecure content or not. This decision is also handled differently by different browsers. For instance, Internet Explorer 10 and 11 display the following message at the bottom of the page:
 

Only secure content is displayed. What's the risk? Show all content.
