We are in the process of migrating from the 61 to 71 environment and we are getting the below error while trying to send the Rosettanet 3A4 Purchase Order to external customer using the delivery methods as HTTPS and providing the necessary Host,port and Location.

The Process model is getting triggered and its failing at the step Send PO Request of the standard PIP action initiator model template

Any help is greatly appreciated

Do you have your server certs defined? The Partner you are testing with, does client authentication? If yes, did you send over your certs to them?

Make sure the certificates are defined right, and your partner certs are deployed on your IS.

Make sure, the HTTPS URL you defined in the partner profile on TN is correct, at times, we might over look and add http/https to the URL.
