Issue

  “Content was blocked because it was not signed by a valid security certificate. For more information, see "About Certificate Errors" in Internet Explorer Help."

The above message occurred when launching QA portal which has a Webdynpro iview on the home page. The QA portal url uses  alias name .

The above messages introduced recently; we Initially suspect this occurred due to recent support packs and host name check becomestrict  .

But our basis team created a alias name for Dev portal as well(which not have before) and the same message unable to replicate in DEV.

Please share your thoughts on this issue.

Thanks
