Setting Redis To Go Up On Heroku

Setting Redis To Go Up On Heroku

On the Redis To Go page for my Heroku app it says: Unable to connect to
instance
I have checked the environment variables via the Terminal and I see that
the Redis To Go EV is the same there as described by the Redis To Go page
on Heroku.
Does anyone have any experience on getting Redis To Go for Python apps on
Heroku to work?
By the way I am on the free Heroku section, and Redis To Go Nano section,
if that makes any difference in setting it up.
Thanks in advance.
