Can't connect to localhost:3000 (other threads didn't help)

Hello programmers,

I shall be adding myself to the list of people having trouble connecting to localhost.

I am running Windows 8, Ruby 2.0.0 on x64 (64-bit). Rails version is 4.1.4

bin/rails server does not work, nor does rails server and rails s

When I run any variant, I get the typical WEBrick booting, etc.

It seems like there are a lot of variables to solving this issue, and thus we'll probably be continually seeing more threads on this subject.

I also read that programming with Ruby in 64-bit is not recommended. That was only one person though. Does 64 really cause troubles throughout various processes? If so, I am willing to uninstall and reinstall a new environment, however with 32.

I would also like to mention that I once connected correctly when first installing my environment and testing it. Now as I proceed to another course, it is not working.

Any help is greatly appreciated guys. As this is a common issue, I will be giving back to others once I figure this out for myself.

Thanks!

Thanks guys!

I'm actually planning on installing Ubuntu. I already have a liveUSB formatted.

After having issues, I just uninstalled my entire Ruby and Rails environment, and redownloaded for a 32-bit development environment.

If anyone reads this in the future and are having problems running 64-bit environments, I suggest uninstalling everything completely and switching to a complete, 32-bit environment.

A simple switch and it worked perfectly from the get go.

Thanks again guys!

I have been encountering the same problem. I am going to try re-downloading Ruby in a 32-bit environment.

Edit: It worked once I reinstalled it! Thanks again! You definitely deserve the reputation point. :)

I would personally suggest downloading free version of VMWare Player and installing a Linux distribution on it (Ubuntu and Mint are probably the most common and most human-friendly), then setting up your development environment there using tutorials (lots of them out there on the Internet). This way you get a more stable experience and some practice with using Unix terminal (in the long run you'll want to switch to that from Windows).

I donu about windows but in my mac I often get an error with the tcp:3000 . If you try and load localhost:3000 and your getting the error server already running. You can try

 lsof -wni tcp:3000
 kill -9 and then the 5 digit pid number of your ruby program running
