When viewing the Newsletters page over an https connection I am unable preview any newsletter. The dialog that is displayed is blank.

newsletter preview blank dialog

The error I get in the console is:

Mixed Content: The page at 'https://stackexchange.com/newsletters' was loaded over HTTPS, but requested an insecure resource 'https://stackexchange.com/newsletters/newsletter?site=stackoverflow.com&suppressPromotion=true'.

This request has been blocked; the content must be served over HTTPS.

When attempting to preview the Newsletters under http everything works fine and the dialog is displayed as expected.

The preview was using the link for the newsletter, which was always set to http.

I have made the link use the same protocol as the one loading the page, which fixes the issue.
