Outbound AS2 - Receive 403 Forbidden in the activity log


I’ve been pulling my hairs (not much left) trying to figure out why I’m getting the “Delivery Failed: java.io.IOException: java.io.IOException: 403 Forbidden”. I’ve check with our trading partner and they’re adamant it’s not on their end and vice versa. This is AS2 going outbound to our partner. The brief message states “Unable to send MDN” but I don’t understand why it would send an MDN when this is outbound. We should be receiving MDN from the partner in a synchronous manner. Please help. Thanks.


Issue resolved. It was a firewall issue.

Most of the times it will be firewall issue…Anyways you got it resolved!:slight_smile:
