It's Solved same Issue for me.

 

This issue we can't fix in Power BI Server, we need to fix this in Power BI Desktop itself, because we can't change the datasource in Power BI server once we published from Power BI Desktop, in power bi server only user name and password we can give  and datasorce connection string we can't change in it.

 

So while creating your Power BI report in Power BI desktop, kindly provide your connection sting like this  "HOST: PORT/SERVICE_NAME"(Don't give any space) instead of your oracle TNS Service Name.

 

It's Worked for me, i think so it will be helpfull for you guys also.
