Using SIM, sandbox AuthorizeNet is timing out on redirection..
[ Edited ]

We are not sure exactly when this started happening, but whenever we try to redirect to an AuthorizeNet payment form there is a 550 error using this URL:


We know SIM is deprecated but as far as we know it should still be working. Does anyone know why this might be happening? We've seen this happen on multiple servers of ours.


Is the server down? If it is, how could we check the status of the server in the future?


In the header after we POST all of the information needed to that URL it will wait for about a minute and timeout with the following information in the header:


  1. Request URL:
  2. Request Method:
  3. Status Code:
    550 Unknown
  4. Remote Address:
  5. Referrer Policy:

If we put the wrong login information it will return instantly that there is an authentication error so the URL seems to still be working.
