Steps to reproduce

If you create a new websocket and use WSS as protocol and access a resource from another orgin even if header Access-Control-Allow-Origin:* exists you get an Security Error.

It works in Edge but not in IE11 after the last group of security updates in May 2017 it worked before this.

This line of code on a onclick event on a button

var con = new WebSocket(‘wss://echo.websocket.org/’);

gives the error in the attached image

  • Hi Fredrik,

    Thank you for the submission.  We are not presently working on features or bugs reports in Internet Explorer outside of security-related issues, i.e., this site is for Edge issues.  If you do require Internet Explorer support, we recommend you contact Microsoft support options for business.

    You can visit https://support.microsoft.com/en-us/gp/support-options-for-business and open a support incident and work with our support team to address this IE issue.
