« Oracle : ORA-12504: TNS:listener was not given the SERVICE_NAME in CONNECT_DATA »

[Zalexatwork]

Hello All,

After changing my pc, I find that I cannot connect to my database, with the error shown in subject.
With my previous pc, the oracle connector generated the tns name just fine and the connexion worked.
I reinstalled the oracle connector, made sure the tns name was the same as it was on my older pc when everything worked, and yet I get the error above when trying to connect.
My IT department is baffled, as the exact same setup still works on my colleagues pc.
We have tried uninstalling and reinstaling different versions of the connector and of power BI, to no avail.
At this point we have no clue as to where to look next, and I am hoping this forum may shed a light on at least possible ideas that we could look into to make it work.
Any help would be greatly appreciated.
Regards,

Alex
