Can't post with new Instagram account

Hello all,

Today I've created a brand new account with proxy and I have trouble with my publication. I'm using MP to posts and it posts correctly but the picture doesn't show on my account.
Look what I see when I browse embedded... Can someone help me please ? thank you

Same problem with another one but WITHOUT proxy... I'm lost

I think everyone has the same problems with new accounts. No solution yet but wait I think
