After downloading SEFAZ Wsdls from Ceará and testing the connection with the service Nfestatusservico4 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 asks for the connection to be TLS 1.2 and even after configuration, these communication errors were occurring. The strange thing is that after downloading the Wsdls from SEFAZ from SP, sending to SP with the same code is working.
Obs.: I used . NET for testing and communicating with webservices
if possible close the question as resolved by marking your comment/reply as correct :)
