[Urgent! Brazilians are without chat!]

At the moment 90% of Brazilian players are not chatting, the message "failed to connect to chat server" appears.
Some more facts about the problem:
-All operators have the same problem (Tim, Oi, Claro, Vivo)
-Yes, we already checked the router's ports!
-No, we were not banned from chat.
-Some are without chat for more than 1 month

We need an URGENT solution or Warframe will be just a reminder of the past!
