My site is set up to default to https

When I upload slides either in the front end or the back end or if I am getting a document from google drive, the resource (pdf) is loaded via http.

So, I get a COR error and the site does not load correctly.

How do I set the slides module to load resources from https instead of http.

I have already set the web.url in system parameters to https

I have also set web.base.url.freeze in system parameters but it still loads resources from http instead of https
