Verify Receipt Sandbox error | Java RuntimeException

Hi,

Over the past week, we have been seeing this error in the sandbox version of VerifyReceipt, with a receipt we have been using for over a year.

{
  "status": 21005, 
  "exception": "java.lang.RuntimeException"
}

This status code is used to signify "Service Unavailable."

Please help.

Thanks,

Wellington | CTO @ Censio
