continuous errors of publication

Bye,
I’ve done a thousand tests, but I don’t understand why in some sites I managed to have it published on instagram and on others not. In this for example there is no way to make it work. The image is 1080 pixels, the login to instagram is fine, there is no option checked andpppure does not want to know to publish and releases me this error, which I paste below. What is it due to and how can I fix it? Thanks
