I know this thread is a bit old, but here is what worked for me.

check the connection using a oracle db client like sql developer or something else to make sure the connection string is working and able to connect to the db with it. If you are using Oracle db Express Edition which is XE, SID is XE and port is 1521 no matter where the web client is running. you can also check this from the web client settings and other places.
