Cannot connect facebook page to instagram page?

Question

[Wolfagen]

I have a page “FairyCoffee” in the Facebook (
email: [e-mail], my problem is that I do’t see it between the options to connect it to the Instagram as shown on the page, what could be the reason of such error.
Looks like an access error, what should I change to have access to it; to be able to connect page FairyCoffee to Instagram account?
