AS2 Error Warnings and Prompts

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

Configuration Errors

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

Transfer Errors

EFT Server 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 can be enabled; SSL negotiation failed; retry transfer

Error decoding certificate

AS2 module cannot decode the Server's or partner's certificate

The receipt was unsigned and a signed receipt was expected

Incorrect certificate used for EFT server or partner certificate

Incorrect AS2-From field

Incorrect "Your AS2 identifier"

Incorrect AS2-To field

Incorrect "Partner AS2 identifier"

Unable to authenticate signature: 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; change user quota allowance or compress/split file.

File is banned

(Uploaded file meets Site’s "Ban" mask) Site configuration does not accept files of this type/name. Change Site's ban settings or let your partner know that files of that type cannot be uploaded to EFT Server.

Use encryption or HTTPS

(Tried to use ‘plain’ AS2 without encryption.)  AS2 configuration must be set to use encrypted HTTP or HTTPS. Refer to Redirecting HTTP to HTTPS 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

 

One possible cause is 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
