Ruby Building Web Apps with Sinatra Your First Sinatra App Your First App

This site can’t be reached

I run produce.rb in the console, and it says that the server is running on port 4567, but when I type http://localhost in my web browser, it says, "This site can’t be reached." Then when I try http://localhost/4567 like in the video, instead of saying, "Sinatra doesn't know this ditty," I get the same error message, "This site can’t be reached." Lastly, after typing http://localhost/4567/apple, I still get the same error message.

Hi Matthew,

To access a port number, you use a colon, not a slash as you have above. So...


should be


Otherwise you will get a 404. Jay mentions this at 4:01 in the video.

Keep coding! :) :dizzy:

Thank you for your response! That was actually a typo on my part while writing my question. Although I had been typing it correctly in the address bar, it had not been working. Well instead of doing it in workspaces, I downloaded ruby and Sublime Text onto my computer, created and ran the file, and then typed "http://localhost:4567/apple" into my address bar and was able to get the text like in the video.

Thanks again for the help!
