Second idea: you aren't explicitly specifying the connection port. 
There is evidence[1] of someone else observing a timeout related to 
1521, which I guess is the DBI default.

What is your cloud database listening on? As the post suggests, setting 
DBI_TRACE will provide more food for investigation.
