Data connection issue

[Tool_Tip]

Dear all,

I am unable to create oracle data connection from enterprise server but able to connect in desktop:

On server getting below error :

ERROR [HY000] [Qlik][OracleOCI] (3000) Oracle Caller Interface: ORA-12170: TNS:Connect timeout occurred

Is Qlik Desktop installed on the same Qlik Sense Server machine?
If not, make sure you have the same TNS configuration file and same access to the Database, user rights, etc.
