This one has me perplexed...
On my website, I am getting Mixed content errors in my console yet when inspecting the source, the urls it says are http are showing as https?
In fact, a search for anything with http:// returns nothing.
Inspection shows:

Yet I get this error:
Mixed Content: The page at 'https://www.immoafrica.net/residential/for-sale/south-africa/?advanced-search=1&st=' was loaded over HTTPS, but requested an insecure image 'http://images.immoafrica.net/aHR0cHM6Ly9yZXZvbHV0aW9uY3JtLXJldm9sdXRpb24tcHJvcGltYWdlcy5zMy5hbWF6b25hd3MuY29tLzU2LzE3MTk4OC8xMjcxOTk0X2xhcmdlLmpwZw==/fb5c609f3c1506a8798dfa620ccf8a15?1=1&width=420&height=310&mode=crop&scale=both&404=default'. This content should also be served over HTTPS.
The page is requesting the following https URL:
…but the server is redirecting that https URL to the following http URL:
Paste that https URL into your browser address bar and you’ll see you end up at the http URL.
Or try it from the command line with something like curl:
$ curl -i 'https://images.immoafrica.net/aHR0cHM6Ly9yZXZvbHV0aW9uY3JtLXJldm9sdXRpb24tcHJvcGltYWdlcy5zMy5hbWF6b25hd3MuY29tLzU2LzE3MTk4OC8xMjcxOTk0X2xhcmdlLmpwZw==/fb5c609f3c1506a8798dfa620ccf8a15?1=1&width=420&height=310&mode=crop&scale=both&404=default'

…and notice th server sends back a 301 response and a location header with the http URL.
So the problem seems to be, that images.immoafrica.net site isn’t served over HTTPS/TLS and instead redirects all requests for https URLs to their http equivalents.
There’s nothing you can do on your end to fix that — other than creating or using some kind of HTTPS proxy through which you make the requests for images.immoafrica.net URLs.
