SSL Error when uploading image

[blackbill1984]

I am getting this error when I try to upload an image for a product:

SSL Error: Invalid or self-signed certificate

Any ideas as to how to fix this?

Is your SSL Certificate invalid or self-signed? 

You can use a SSL Certificate checker tool to see if it works properly. 

Here's an example of such a tool:-
