ORA-12170 Error connecting to 18c XE

HI I am trying to Connect Oracle 18c XE using DOA 4.1.2.0 from Delphi 2009. Unfortunately I am getting ORA-12170 error. Connecting with SQLPLUS is working fine, TNSPING is working fine. Anybody with a godd idea ?
 
Is your Delphi application using the same Oracle Client as SQLPLUS? If so, can you let me know the Oracle Client version?
 
In the mean time i deinstalled the client completely and did a reinstall, but the error still raises. SQLPlus is workig correctly, TNSPING works, but still get the message timeout
 
In your application code, can you do the following call after attempting to connect to the database?

ShowDOAInfo(nil);

Send me a screenshot of the info screen.
