serve dont connect

The server, on the aternos website, creates normally. But when I go to connect, in the game, does not connect. And the red ball appears offline server (and yes, the server was online). And it occurs when I enter the world of my friend, it appears "could not connect to the world", maybe it may be related. And we are using the same version.

If some things are spelled incorrectly, I'm sorry. I am from Brazil and used the translator.

Today I work using only Dyip. But yesterday was not, not even by the game itself, when your friend creates the world and you go to the second page and enter.
