Have you tried Huabao protocol?

I dont any idea about Huabao protocol. How can I solve it?

Just use the right port.

How can I get right port?

I already told you the right port - Huabao.

I think Huabao port is 6015. But did not work.

I would recommend to read documentation before asking any further questions.

Hi, try with port 5013, work for me.

Você conseguiu deixar online?E qual a porta?

Still can not work. Feeling upset.

Vc enviou o protocolo desse novo modelo?

o que você quer dizer com protocolo de envio? Seu protocolo Huabao

Também não consigo deixar online

A porta huabao e 5015
