Fiori Launchpad designer or LPD_CUST failed to genereate the iframe with https

[wanhua_liu2]

I try to configure a tile to embed a BP system

When I visit the tile, the page is empty. Check the DOM in Chrome developer tools, the src of embed iframe is http, it should be https.

In the console, I get the error messages below.
core-min-0.js:75 Mixed Content: The page at 'https://domaina:13802/sap/bc/ui5_ui5/ui2/ushell/shells/aba…sap-language=EN&sap-sec_session_created=X#BusinessPartner_LPDCUST-maintain' was loaded over HTTPS, but requested an insecure resource 'http://domaina:44310/sap/bc/gui/sap/its/webgui?%7etransact…ash=1&sap-client=770&sap-language=EN&sap-ie=edge&sap-theme=sap_bluecrystal'. This request has been blocked; the content must be served over HTTPS.

In the SM59, I had configure the destination with SSL active.

In another Gateway server, I configure the destination with a not exist domain. the src of iframe is https.

I don't know, how to make the src of iframe with protocol https.

Below is the configuration.
