Hi,
Glad to hear that you are getting started.
One of our community had what looks like a similar problem with connecting to the localhost, see the discussion here:
If you are still struggling after having a look at that then let us know in this topic and we’ll see if we can help more.
…and if you could post some more code to give context it would make things a little easier for us to see what’s going wrong.
Thanks,
David.
