make sure your api file says this for the live url:

const LIVE_URL = 'https://secure2.authorize.net/gateway/transact.dll';

in
[xcart_dir]/modules/BCSE_Authorizenet_DPM/lib/sdk-php/lib

also make sure your server can connect using tls 1.2

if using openssl as your ssl libary (this is found under security settings in xcart admin area (I think),

you can update it, if it fails the test below:

Test your server's openssl version:
