Summary

The basis for a successful connection is the correct Application Server or IP and their Instance Number.

Step-by-step guide

Two ways to check for your HANA Server Name or IP and the Instance Number.

Log into your Eclipse:

SELECT * FROM "SYS"."M_SYSTEM_OVERVIEW"

Try to access it in your browser on the following page:

Enter:
https://<Application Server>:43<InstanceNumber>/sap/hana/xs/lm/
OR
http://<Application Server>:80<InstanceNumber>/sap/hana/xs/lm/

(e.g. http://10.3.4.567:8011/sap/hana/xs/lm
or
https://saps75db00.wiesbaden.bluetelligence:4311/sap/hana/xs/lm)
