Xfinity account is already linked to another Peacock error

Last week I was able to connect my existing Peacock account to Xfinity but today it is no longer connected. I have tried reactivating but I continually get the error “your Xfinity account is already linked to another Peacock account”. I don’t know what else to do as I have only connected the one account and I can’t watch anything on Peacock now.
