I can’t reconnect to my instagram account

I’m using the plugin for a little while now and everything did go well. However suddenly I got a error regarding my instagram account. The feed wasn’t connected anymore so I tried reconnecting but when I create a new token and go back to WordPress I get a message that I don’t have the permission to view the page after connecting, but I’m the owner of the website?

So now I can reconnect my account, how can I solve this?
