Error loading images in Templates

I appreciate your support in solving a problem in the Phplist configuration.
I installed the latest version of Phplist in my hosting, but even though I place the URL of the images well in the templates, they do not link. It shows me the following error:
Image https: // www. … …/uploadimages/image/lopogh.jpg => does not exist
Errors have been found, the template has NOT been saved!
