REST receiver adapter with HTTPS url

Former Member — Sun, 18 Mar 2018 05:27:34 GMT

We are calling a third-party REST web service which is hosted outside of our network. The https (secure) call fails to bring back the response. Where as the http call is a success.

The https call gives below errors:

1. In the communication channel message log: java.io.EOFException: Connection closed by remote host

2. In the ICM trace we find the error as: ERROR during SecudeSSL_SessionStart() from SSL_connect()==SSL_ERROR_CONNECTION_LOST

I think a low level network trace could help you further.

If the HTTPS connection is initiated by ICM set ICM trace level to 3.

In Unix/Linux try tcpdump on Windows try Wireshark or Microsoft Message Analyzer tools to capture SSL/TLS handshake.

Best Regards,

Antal

Import the certificates chain in your netweaver and try again. If its still failing try to check a firewall issue (lot of firewalls has the ports closed by default) with a telnet from your PI instance or something like that.
