AS2 Error Warnings and Prompts

EFT provides error warnings and prompts when you are configuring the AS2 module and when you are sending/receiving files using AS2.

AS2 Configuration Errors

EFT presents a prompt and disallows changes to AS2 configuration in the following instances:

• Settings are enabled that require a partner AS2 certificate and no certificate has been defined for that partner

• Settings are enabled that require EFT’s AS2 certificate and no certificate has been defined for EFT

• Settings are enabled that require the partner’s or the Server’s identifier and no identifier has been defined for the partner or EFT

• The chosen certificate is set to expire in 30 days or fewer

• A certificate being imported is a combined certificate

• You open the AS2 Send File dialog box and click OK or Apply without specifying a partner profile.

AS2 Transfer Errors

EFT provides the following transfer error messages. When you receive one of these errors, you should examine your AS2 configuration and other Site/User settings. Certain messages are simply an indication that the configuration is working as designed. For example, if your AS2 outbound configuration has a filter mask to ban files with a .zip extension or if the Site's configuration bans files of this type on the Server, you will receive a banned file message when a user attempts to send files of this type.

Error	Possible Cause/Solution
A network error occurred	Verify AS2 server address and port; ensure there is a connection between the two servers and nothing is blocking the connection; require SSL certificates from connected clients might be enabled; SSL negotiation failed; retry transfer
Error decoding certificate	AS2 module cannot decode EFT's or partner's certificate. Make sure the certificate is not corrupt or is of an unsupported format. Also check that the certificate is a single certificate and not multiple certificates inside of a certificate.
The receipt was unsigned and a signed receipt was expected	Incorrect certificate used for EFT or partner certificate
Incorrect AS2-From field	Incorrect "Your AS2 identifier"
Incorrect AS2-To field	Incorrect "Partner AS2 identifier"
RSA Error: Inadequate amount of padding in encrypted message	AS2 module cannot verify signature of signed incoming message; possible problem with identifiers; sender might be using incorrect identifier; AS2 MDN cannot be verified
Timeout occurred while sending MDN	Firewall blocking receipt send (MDN blocked)
File already exists, Message with duplicate ID and different payload was received.	(Tried to overwrite existing file and corresponding policy is set to Reject.) AS2 configuration does not allow overwriting files of same name; change AS2 configuration to Accept these files or move/rename files after they are received.
Quota exceeded	File is too large. User configuration does not accept files of this size; Specifying a User Disk Quota or compress/split file.
File is banned	(Uploaded file meets Site’s "Ban" mask) Site configuration does not accept files of this type/name. Banning Unwanted File Types or let your partner know that files of that type cannot be uploaded to EFT.
Use encryption or HTTPS	(Tried to use "plain" AS2 without encryption.)  AS2 configuration must be set to use encrypted HTTP or HTTPS. Or use redirection; refer to for details of redirection.
Unable to decrypt message, RSA Error	Inadequate amount of padding in encrypted message. AS2 module cannot decrypt encrypted incoming message.
HTTP error: 400 Bad Request	Receiver/sender has incorrect or missing certificate; Connection problem of some kind
HTTP error: 401 Unauthorized	Authentication failed for username/password; IP address is blocked
HTTP error: 403 Forbidden	Incorrect folder location, Mailbox path; do not have permission to remote folder/path; AS2 is not enabled/supported on receiving side
