Instagram feed not found

Hi! I have a problem with this pluggin (or i think that…). So, 4 days ago the pluggin was working fine but since 2 days i got the error message “Sorry, Instagram feed not found”.
I reinstall plugin, reconfigure and it’s not working.

I think that can be Instagram error or Instagram account api bloqued, it’s possible?

Somebody know why occur this issue?

Thx in advance!
