iaik.security.ssl.SSLException: Peer sent alert: Alert Fatal: internal error

Hello, guys.

Wonder if any of you might have had the same issue and what you did to solve it.

This a REST interface( receiver ). Server certificate has been imported.

Using Postman or SoapUI works fine.

We found SAP NOTE

which says some parameters should be set. It was done but we still receive the error.

HTTP headers have been added.

We also used openssl and got the error if -servername is not used in command. After it was added we were able to connect.

I'll be very thankful if you can help.

    Hi Alejandra,

    As per my knowledge , REST Adapter is one of those adapters that used JVM library , instead of IAIK.Also , from your XPI Inspector Screenshot I can see you are on TLS1.2 So , probably you can try couple of things:

    1. Either make Rest Adapter uses IAIK Library instead of JVM. Follow Note 2229837.

    2. Or update your JVM to accomodate Rest Adapter communicate over TLS 1.2 . whats your current version , please let us know.

    Regards,
