We are unable to connect to an Oracle database from our on prem Power BI Report Server using Desktop with Direct Query or with Report Builder's Paginated reports. The Oracle connection test connection passes on the Report Server but the preview of a Data Set does not work on the Report Server and says preview is unavailable. On the Report Builder, the data source connection does not successfully connect and we recieve execution errors. Import works with dashboards created in Desktop but not Direct Query. Any help would be appreciated.

We have the oracle client installed with the associated TNS names file setup.
C:\ora32\product\12.1.0\client_1\network\admin
Tnsnames.ora file contains the following:
# tnsnames.ora Network Configuration File: C:\Oracle\product\10.1.0\Client_1\NETWORK\ADMIN\tnsnames.ora
# Generated by Oracle configuration tools.
