After downloading the SEFAZ WSDLs from Ceará and testing the connection to the NFeStatusServico4 service I got the error:
Falha na solicitação com resposta vazia.
or in English
The request failed with an empty response
The new version of NF-e requests that the connection be TLS 1.2 and even after configuration, these communication errors were occurring. The strange thing is that after downloading the SEFAZ WSDLs from SP, sending to SP with the same code is working.
Note: I used .NET for testing and communication with webservices
