Solved! It was a right error
I use fillezilla and it seems that 755 rights don’t go on each year folder it stop at wp-content/uploads.
Thank you for your help!
looking with an ftp client I see files in wp-content/uploads/2018/12 but always error message!!!
I can’t see them in WP in media library I’ve always hourglass.
I changed permalinks. I tried to upload from 3 computers.
All my old articles and pages display normally.

Default theme was twenty twelve.
I use wordpress documentation on how to activate https and add plug-in Really Simple SSL.
I tried it and reload last version but I’ve always the error.
I tried to deactivate all other plugins and changed theme without result.
