Error when connecting to S4HANA system through Eclipse with ADT

[salah_zinet]

Hello Experts,

I installed Eclipse (2020-03) and added ADT on it, I created a project for the older SAP ERP Dev system without any problem, but when creating a project for my S4HANA system it stops on the stage: Retrieving compatibility information from backend system.

After activating Trace on Eclipse and comparing the two connection Logs,

I suspect this error:

[ERROR] Initialization of repository destination adt.tmp_1588827698049 failed: Connect to SAP gateway failed
Connection parameters: TYPE=A DESTINATION=adt.tmp_1588827698049 ASHOST=XXX.XXX.XXX.XXX SYSNR=00 PCS=1

Could you give me some help on that ?

Thanks in advance,

My best regards.
