I am just trying to move from SE80 to Eclipse for ABAP developments.
I installed Eclipse followed by installtion of ABAP development tools using https://tools.hana.ondemand.com/juno as source of software tools.
I am unable to connect SAP
systems which are already available in SAP logon pad. I can see systems while creating new project but when I am trying to login into system using correct credentials eclipse is throwing error.
I am putting all details below.
Please help me in getting a solution of this problem.
Thanks.
Error which is occuring -
Eclipse Version - 4.2 Juno
System Details: Please note there is some warining regarding SNC but I am not sure that is this creating some problem.
Network connection preferences in Eclipse

Hi Rahul,
using SNC is recommended for security reasons, but it is not mandatory.
Does the corresponding SAPLogon entry work error-free if you try to connect with SAPGUI?
Best regards,
Marco

Yes Marco. It is working perfectly when I am trying to use SAP Logon.

Hello Rahul.
We are facing similar issue while connecting to Gateway system from Eclipse. However, the IP address referring to the SAP system is a natted ip and not the direct ip/hostname.
Is your problem resolved? If yes, what did you do?
Thanks in advance.

Hello,
we have seen similar issues related to the resolution of host names or IP numbers.
Please try the following:
Add the IP number you are using in the system connection (in Rahul's case: 170.167.250.16) to profile parameter gw/alternative_hostnames of the application server you are trying to connect to.
If that does not help, we need the Eclipse support information (support.zip) for deeper analysis.
Best regards,
Marco

Hi Marco,
thanks a lot for the hint. I assume this stept would also work if you enter the internal DNS name e.g. SID.services.domain. I've implemented it with the IP address but I think DNS entry is more comfortable and flexible in case IP changes.
Best regards.

Hi Marco,
Can you please tell me where can I find below parameter. I am not sure where to add the IP as mentioned below.
"profile parameter gw/alternative_hostnames of the application server you are trying to connect to."
Thanks,
Saravanan.

Hi Saravanan,
please use transaction RZ10 and select the instance profile. Select "extented maintanenance" and than add the parameter.

Hi Marco,
I am facing ditto issue when access sap via SAP Hana Studio, i have added gw/alternative_hostnames in RZ10. But still issue.
Please help .
Thanks,

Hi Amit,
just to be sure. To activate the parameter a system restart is required. Have you restarted the system before trying the connection again?

I ran into similar issue; I was able to connect to my SAP( S/4 1909) server from GUI; but getting error from Eclipse (ver. 2020-06) " Logon to system <sid> failed (partner '<IP>:<PORT>' not reached)"; during troubleshoot , it was discovered that, company's firewall is blocking the port num. Eclipse uses to connect.
