This means the relay response URL used by Magento/your website is not returning a successful response to Authorize.Net in time (5 seconds). As a result Authorize.Net is assuming the page is not functioning and displaying that message.
You need to verify that the URL you provided is correct, reachable from outside your network, and responding in less than five seconds.
