Why did the Gateway Transmission Fail due to Error: com.helger.as2lib.disposition.DispositionException: automatic-action/mdn-sent-automatically; processed/error:unexpected-processing-error, in Vault?
If this error is unexpected, please try the transmission again. Should the error persist, use an alternative method of transmission to the Health Authority (HA). This error means there is an issue with the certificate with the HA. To resolve this issue, work with the FDA further on updating the certificate.
