Error loading .dcm

Hello,

I installed the plugin a few months ago and had no problems displaying multiple images in a gallery.

Once I installed a SSL certificate, I started getting the following error on my page. No matter I tried, the error comes.

RequestError: An error occurred while downloading ‘https://www.msk-wissen.de/wp-content/uploads/2018/07/IM-0001-0047.dcm’ (http status: 0)

When I open the fullscreen mode I also receive the error.

When I remove the “s” from https and refresh the URL, the images work.

How can I get this working and keeping the SSL on my page?
