Can't create remarketing in google ads, images won't load?

Question

contextual advertising

Hello. I can’t create kms companies in google ads, pictures are not loaded and, accordingly, I can’t see the preview of ads.
I attach the screen, I tried different options, nothing happens, what could be the problem? Tell me please.

You may be uploading unsupported image formats. Have you tried downloading from another device on a different network? Perhaps the matter is in the hosts file, do you have software that could make changes there? Have you disabled ad block?
