I keep receiving the following messages every time I try to log on to localhost:4567 using Sinatra.

This site can’t be reached localhost refused to connect. Search Google for localhost 4567 ERR_CONNECTION_REFUSED

this might be basic, but are you using http://localhost:4567? some browser clients add the http:// automatically, others don't.

secondly, do you have a firewall currently in place?

Yes, that is the link I am using. Also I disabled my firewall but its still not working.

Also this is the message I receive when I run the program on ruby.

"treehouse:~/workspace$ ruby produce.rb

Hello everybody! I've followed all the instructions to install Sinatra to my pc and run http://localhost:/4567/apple and I still keep receiving the same message: "This site can’t be reached localhost refused to connect. Search Google for localhost 4567 ERR_CONNECTION_REFUSED"

This is the link that I am using for reference http://sinatrarb.com/ as it seems to have the latest commits and updates.

Can somebody help me? Workpaces runs ok no problem but I want to build and run my Sinatra app in my computer and localhost. I will really appreciate your help! Thank you so much! Happy coding! ;)

are you trying to navigate to localhost in a browser, or clicking the eyeball in the top right corner of the workspaces screen? from what I remember, workspaces doesn't output ruby to your machine to preview through workspaces, so you have to use that eyeball.

Hi, Yes, I am trying to access it through a local browser.

Hi, MaryAnn Eleanya ,

Because your pasted shell prompt includes treehouse:~/workspace, I can see that you have written your code in Workspaces. But http://localhost:4567 is a URL that you will only want to use if you are running a Sinatra app using a Ruby interpreter that you installed on your personal computer, not Workspaces.

The "Your First App" video includes directions both for running a Sinatra app on your personal computer, and for running it within Workspaces. It's important not to confuse the two. The Workspaces directions begin at 5:03 in the video. Follow those, and you should be able to connect.
