错误:CodeIgniter上的连接重置(Firefox)

I have a problem,

On some computers the following message appears in the browser when I try to access the link from my application:

Connection reset (Firefox);
This page can not be displayed (IE).

Cause of the problem: Warsaw (security module of Bank of Brazil, Caixa Economica...)

There's something blocking access to the application for some reason.

Do not use antivirus on my computer.

Resolution: Uninstalled Warsaw and Installed User Agent Override and set User agent Linux/Firefox

If you had any way to get around this block, be sure to comment.

Thanks!
