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

[Former Member]

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!

Hi Guarav,

it just contain this line:

# localhost name resolution is handled within DNS itself.

127.0.0.1 localhost

# ::1             localhost

But I've tried it also yet with additional information you provide so it looks now like:

127.0.0.1 localhost.localdomain localhost

But problem is not solved...

Hi Andre,

What about the second entry i.e for system IP with hostname ? Please maintain it also as suggested earlier.In resume reconfirm for the firewall disability to try again.

Now it looks like:

127.0.0.1 localhost.localdomain localhost

::1       localhost.localdomain localhost

But will also not work.

But for better understanding please - as I describe netstate will not show any service listen at 21212.

So how could be connection to 21212 possible without any listener?

Andre,

Please create SAP system entry in saplogon pad and try to connect.

Anand,

thank you very much it works now.

So to sumarize:

I setup ABAP_Trial_7_02_SP11_Win_64_bit_Version_3_387_GB but also requiere ABAP_Trial_7_02_Win_64_bit_1_84_GB because it contains the GUI directory I need for setup.

The secret of port 21212 will still be a secret

My first impression - there're really less transaction given.

Is there any way to include other modules as eg. SD in the trial?

Thank you very much!

Hi,

Could you please share host entries which you maintained at your end or try to maintain as like

127.0.0.1 localhost.localdomain localhost
<IP of server>  <Hostname>

Hi Anand,

I've the same issue as in link SAP GUI installation error described - no GUI directory (and in my case also no Part2 to extract).

But I found a second trial called ABAP_Trial_7_02_Win_64_bit_1_84_GB and this contains a directory called GUI.

I can setup GUI so okay first stap is solved - GUI is installed.

But when I run it the Login button is deactivated and it seems that the problem with the connection is now only postpone to connection after setup ...

Maybe netstate result will be needed also?

Hi,

I disable Firewall & UAC and add "127.0.0.1 localhost" to vhost.

Unfortunately result is the same as before and I get the error that connection to port 21212 is not possible.

Any further ideas why that happen?

Thank you
