Oracle ORA-12154: TNS: Could not resolve the connect identifier specified

Hi there, 


I'm having this issue when I tried to connect Oracle OneData to PowerBI. Note that I received the pbix file that I received is already complete and now I'm trying to reconnect the database from my end.






I have tried some solutions here like checking the tnsnames.ora file, file path and troubleshooting.


Any other solutions that my fellow power bi community may know? Thank you.
