Hi everybody,

we got an reminder from SAP that our X.509 SSL client certificate in our HCI (SAP Cloud Platform Integration) is about to expire on 5th March 2018. We didn't replace the certificate because we thought that this is not relevant for us due to the fact that we have stored the used certificate in the ERP system. We tested our integration on 6th March and it still works.

But since this date we've getting emails daily that the communication S-User we use for the integration between ERP and C4C tried to log onto the system but has 5 failed attempts. See screenshot.

Does anybody else experience something similar?

Does anyone know whats the reason for this? and what to do now?

Best regads and sincere thanks,
