Hello Markus,
Yes. The SCC is installed on my laptop itself. I did a telnet using port 3300 from my laptop to the ERP system which I launched from CAL. It connected. But still the timeout error from SCC when using RFC protocol over port 3300.
Connecting to the ERP system's IP on HTTP using 50000 did not time out.
HTTPS over 50001, 443, 44300 all timed out.
Regards
Suneet
