Question
Rails app under subdomain returns blank page
- Posted November 8, 2014
-
I have a domain with godaddy : bewotechno.com. This is the main domain, and has a website hosted on another hosting.
-
My rails app is deployed at digital ocean with Nginx-Unicorn-Ubuntu stack.
-
I created a sub-domain called support.bewotechno.com, and pointed it to this droplet. I get the following response (on the browser):
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<title>support.bewotechno.com</title>
</head>
<frameset rows="100%,*" border="0">
<frame src="http://104.131.114.186" frameborder="0" />
<frame frameborder="0" noresize />
</frameset>
<!-- pageok -->
<!-- 04 -->
<!-- -->
</html>
I’ve tried to do some debugging, and the problem is definitely with the rails app.
What I tried, and some interesting results :
- The app is showing when i enter IP address.
- With the domain support.bewotechno.com, I checked rails logs, and a GET request is hitting the app, and controller#view is being accessed
- I’ve tried checking config files of nginx, unicorn. Absolutely no problems there. The request is hitting my rails app.
How do I get the page to show up with the subdomain? What’s going on here?

support.bewotechno.com points to 184.168.221.26 which is run by GoDaddy. It looks like you accidentally created a “forward” to the IP address instead of an actual DNS record for the subdomain, which explains the iframe pointing to your droplet’s IP address:
You need to add a CNAME (Alias) DNS record instead, set the “Host” to
support, and the “Points to” field to@and make sure you delete the forward rule that you created using GoDaddy’s control panel.
