There are several places on LoE that are unreachable for earth ponies so the devs put teleports near these places so that earth ponies can get there. This is the case for some towers on Cantermore and Crystal Kingdom.
However, there is a big cloud on cloudopolis near the rainbow factory that has constructions on it so ponies can sit there and also bees to kill. This looks like an important part of cloudopolis but it's only reachable by unicorns and pegasus, but not for earth ponies which I think is pretty unfair and doesn't make much sense.
Please add a teleport for earth ponies.
