To test your server's connection to the SWRemote server, you must have access to the SWRemote admin site. The site can be found by clicking the following link and entering in your admin credentials:
Once there, navigate to the Master Accounts tab -> scroll down below the Payflow Settings-> Press Test Settings.
If successful, it will turn Green.
If the link does not show a solution to your error, please give the SWRemote Support Team a call for assistance at 1-800-566-6940.
