Hello Sai,
This note is not relevant for PI 7.5 If you check the support packages and patches section, it only is applicable for 7.30 / 7.31/ 7.40. As this was working fine on 7.40 version of your PI Server, the issue lies elsewhere.
The error points to a "Bad Certificate". Can you let us know,
- If this was a migration or an inline upgrade?
- If Migration, check if the SSL certificates and client authentication ( if applicable ) are working loaded as required.
- If upgrade, has something changed on the Service Provider with regards to the certificate?
I would also suggest using : 2157425 - New Feature: Client side HTTP Tracing for HTTP_AAE adapter
to trace your RAW HTTP Payload and see at what point the error occurs..
Regards
Bhavesh
