I am setting up as2 connectivity to a partner. I can send them data but when the MDN comes back it shows this error “MDN Disposition: automatic-action/MDN-sent-automatically; processed/error: unknown-trading-relationship”
I have verified all certs on their side and mine. The partner says they are sending a signed MDN. I dont know why it is failing.
I did notice that partners MDNs that are working have a content type of multipart/signed where the MDN from this partner is multipart/report. They dont know where that is being set.
