GUI setup error: Could not connect to host localhost on port 21212

522 Views

Hi,

I setup the trial of SAP 7.02 on Windows 10 and installation had been without problems reported.

When I check SAPMMC everything seems to run but when I like to setup the GUI I get an error:

Error while connecting to communication partner - see preceeding messages.

Could not connect to host localhost on port 21212.

java.net.ConnectException: Connection refused: connect

java.net.ConnectException: Connection refused: connect

When I check "netstat -an" there seems nothing to listen for port 21212.

Aslo the start.htm point to an URL:

http://localhost:8000/sap/bc/gui/sap/its/webgui?sap-client=000

If I call this URL I get an error 403 Service can not be reached.

I'm using Windows 10 with 4GB and JAVA JRE 1.8.

Maybe JAVA version is not compatible with SAP 7.02 ?

Can you help please?

Thank you in advance!

Andre
