Error Response 3 with Reason Code 21

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?
