I already configured my cluster and added everything that had to be added, but my cluster never finished being created and it took several hours like this and nothing happens.
Hi @Emanuel_Garces and welcome in the MongoDB Community 
!
As you can see here, their was an upstream issue at AWS on Dec 7th and cluster creation or repair have been delayed.
It should be all good now. Let me know if that’s not the case.
Cheers,
Maxime.
