Hello!

Make sure you follow the guidelines for importing and connecting certificates to profiles as specified in the AS2 documentation, specifically for Outbound signing certificates: https://docs.aws.amazon.com/transfer/latest/userguide/managing-as2-partners.html#configure-as2-certificate.

It is possible for the Inbound workflow to succeed but still have issues with the Outbound workflow. Although there are less points of failure because you are using the same certificates and private keys for encryption and signing, it is still useful to review the following items:

• The LOCAL and PARTNER profiles are configured correctly for you and your trading partner
  • You receive your partner’s encryption/signing public key and attach it to the PARTNER profile
  • Your encryption/signing public key and private key are imported and attached to your local profile for both SIGNING and ENCRYPTION.
• The correct profiles are attached to the Connector such that you are configured to send a message to your trading partner
• You sent your encryption/signing public key to the partner and your partner attached the public key to their server.

Please open a support ticket if you are still experiencing this issue
