Error Response 3 with Reason Code 21

kitaryan — Mon, 28 Jul 2014 17:46:22 GMT

I have a Sandbox account setup that was working fine all up until randomly on this past Friday I started to get an error code of 3 with a response code of 21.

This website says:

An error occurred during processing. Please try again in 5 minutes.

Now 3 days later, I'm still getting this same response.

Any clues of what would cause my Sandbox to randomly stop working?
