Strange Cloud Logo no music

While writing new post, I’ve added some tracks from soundcloud but unlike always, they just dissapeared from the text editor (they appeared in the preview page).

When I published the post, all the widgets just displayed a cloud logo, like this.

I’ve deactivated jetpack but still not working.
The other soundcloud widgets, in past posts still working well.

Any ideas?

Thanks in advance!
