How can I connect to an Oracle Autonomous Data Warehouse with a 3rd party IDE (DataGrip)?

I'm trying to connect to a Oracle Autonomous Data Warehouse database with Jetbrains DataGrip. Oracle provides me with a wallet file (a zip), with contains tnsnames.ora, a keystore, ojdbc.properties, and some other files. I'm having a lot of trouble using this information to connect to the database using DataGrip. I found a thread on the DataGrip support forums, but I'm not having any luck with that either. Jetbrains support thread: https://intellij-support.jetbrains.com/hc/en-us/community/posts/360001792539-Connect-with-Oracle-Cloud Relevant Oracle documentation: https://docs.oracle.com/en/cloud/paas/autonomous-data-warehouse-cloud/adwud/connect-using-client-application.html **What I did:** 1. Created the 'TNS_ADMIN' environment variable and set it to: C:\\Users\\xxx\\Documents\\[folder with wallet files] 2. Added the Oracle JDBC driver files (ojdbc8.jar, osdt_cert.jar, oraclepki.jar, osdt_core.jar) to the standard Oracle driver in DataGrip 3. edited the 'sqlnet.ora' file to include the path to the wallet files 4. Added the following to the Data Source VM Options: -Doracle.net.tns_admin=C:\\Users\\xxx\\Documents\\[folder with wallet files] -Djavax.net.ssl.trustStore=truststore.jks -Djavax.net.ssl.trustStorePassword=[password] -Djavax.net.ssl.keyStore=keystore.jks -Djavax.net.ssl.keyStorePassword=[password] -Doracle.net.ssl_server_dn_match=true -Doracle.net.ssl_version=1.2 5. Set connection type to URL only 6. Tried different connection strings in the URL field:

:oracle:thin:@//adb.eu-frankfurt-1.oraclecloud.com:1522/xxxxxx_adw1_high.adwc.oraclecloud.com?TNS_ADMIN=C:\\Users\\xxx\\Documents\\[folder with wallet files]

:oracle:thin:@xxxxxx_adw1_high.adwc.oraclecloud.com?TNS_ADMIN=C:\\Users\\xxx\\Documents\\[folder with wallet files]

:oracle:thin:@//adb.eu-frankfurt-1.oraclecloud.com:1522/mnr6yzqr22jgywm_adw1_high.adwc.oraclecloud.com

**Result:** Connection to ADW1 failed. IO Error: Got minus one from a read call, connect lapse 32 ms., Authentication lapse 0 ms. I have also tried using the 'Service name' and 'TNS' connection types and filled in the info from tnsnames.ora. No dice, same error. Also tried explicitely setting the 'tcp.validnode_checking' parameter to null. (The connection works fine with sqldeveloper) What's the proper way to do this?
