This error was caused by an Internet connectivity problem and the merchant was able to work with their Internet Service Provider to reset their connection and once that completes, the system returned to normal. An additional check that can be used is to start a browser and visit a known good web site and see if you can access the site without issue. If the site can open without issue, attempt to connect to and see if a site loads without error. If it does, the Internet service may not be the problem at this time.
