Thank you! The information you shared fixed the connection issue for me, but there's still another problem: Evo is not detecting/receiving the incoming messages. My installed version is v2.3.4 Have you ever run into this and do you know any solution?

@DiegoSalvati Acabei de encontrar a solução para o problema em outra Issue do Git. Aqui está a solução: #2224 (comentário) Comigo funciona perfeitamente, espero que ajude você também.

Obrigado! As informações que você compartilhou resolveram meu problema de conexão, mas ainda há outro problema: o Evo não está detectando/recebendo as mensagens recebidas. Minha versão instalada é a v2.3.4. Você já se deparou com isso e sabe como resolver?

eu tambem estou com o mesmo problema

Hi I solved it finally upgrading to the 2.3.6. Though now when connected, if I receive messages the push notifications are not showed anymore on the screen when my iphone is blocked. Anyone with the same problem?? thanks again
