Instagram Token invalid??

since a few days (weeks?) the photos no longer load. I get this message:

“Something is wrong. Response takes too long or there is JS error. Press Ctrl + Shift + J or Cmd + Shift + J on a Mac to see error in console or ask for free support.
Instagram token is invalid or expired. Please reset token and sign-in again to get new one.
Admin warning: there is one or more private user in this feed (). Their media will not be displayed. ‘

I have already made a new token, but nothing helps. Hopefully someone can help here?

Thanks in advance!
Steven
