DirectQuery Oracle database connection issues
andershh check out this blog post and scroll to the end where there is a solution provided to the error message that you're getting. It talks about ssas but maybe it also works in your case of Oracle.
ankitpatira - After taking a look at the troubleshooting guide you linked to, I am almost certain that the issue is due to my firewall blocking some of the ports that the on-premises gateway needs in order to communicate with the PowerBI service. Will mark your post as a solution if testing connection with new firewall settings shows that it works. Thanks for sharing the troubleshooting guide!
dimazaid I have tried looking at the log area for the gateway (as specified in the troubleshooting), but there are no logs there. Thanks for the suggestion!

After opening the ports specified in the troubleshooting guide linked to by ankitpatira the problem still persists.
However, dimazaid I was able to find some log files here: C:\Users\PBIEgwService\AppData\Local\Microsoft\on-premises data gateway\Gateway*.log
Looking at the latest log file it appears this is the main error causing the issue:
GatewayPipelineErrorCode=DM_GWPipeline_Gateway_DataSourceAccessError --->
[1]Microsoft.PowerBI.DataMovement.Pipeline.Diagnostics.GatewayPipelineWrapperException: Substituted: ArgumentException:<pi>System.ArgumentException: 'integrated security' is an invalid connection string attribute

ved Oracle.DataAccess.Client.OracleConnection.set_ConnectionString(String value)
ved Microsoft.PowerBI.DataMovement.Pipeline.GatewayDataAccess.OracleConnectionProvider.<OpenConnectionAsync>d__0.MoveNext()</pi>dimazaid or ankitpatira - do you know what might be cause this issue?
