I am using NAAF v5.6 .I am configuring for Email OTP. It is showing me folllowing error.

Code:
Cannot send OTP. Auth extension not supported by server
1. How to check if internet is working ?
2. Access to terminal so I can ping ?
3. How to configure Proxy setting inside naaf . Because to start internet we use proxy setting inside internet explorer like https://proxy.com
there is no need of usernsme and password.
