Some images not showing in some desktop browsers

Hi,
I have a problem with some images not showing up in some desktop browsers. Safari works everywhere, Chrome works on mobile but not on desktop, Opera works on mobile but not on desktop.

I have been going through similar problems that I found here on the forum and tried the following solutions without success (always clearing cache in between):

1. Disabled all the plug-in’s.
2. Disabled lazy load.
3. Changed to https in WordPress settings and using “Better Search Replace”.

But I am uncertain about the success of the last step, as the liks still seams to use http and not https when I check with the inspecting tools, I don’t know why that is.

Any idea how I should proceed?
