Heroku custom domains
I've setup two custom domains for my Heroku app.
example.com example.com.herokudns.com
*.example.com wildcard.example.com.herokudns.com
Domain configuration
I configured my domain as follows:
I added a CNAME Record for * pointing to wildcard.example.com.herokudns.com.
Works fine.
I forwarded my URL using GoDaddy's Domain Forwarding tool, because I can only specify IP addresses as A records.
Problem
The domain forwarding points to example.com.herokudns.com. Unfortunately GoDaddy automatically prepends http://, so it actually does not open my app and instead shows a Heroku message:
There's nothing here, yet.
Goal
Setting up my GoDaddy root domain to point to my Heroku app.
Note: GoDaddy automatically added an A record for @ pointing to >>++FWD1++<<
Cloudflare does the job!
Finally, I achieved my goal of using my naked domain as host by choosing CloudFlare to handle my DNS configuration.
Resources:
- CloudFlare allows
CNAME Records to be the naked domain
- How
CNAME Flattening works
Note: CloudFlare has a pretty good documentation and setup process, you just need to:
- add your domain to CloudFlare
- follow the CloudFlare setup guide
- updating your nameservers (in my case GoDaddy) to point to CloudFlare
What did you set your DNS to forward to? I had this same problem, but solved this creating a Heroku DNS entry for www.myapp.com. Heroku creates a DNS target of www.myapp.com.herokudns.com.
Here is my setup:
- DNS forwarding to www.myapp.com
- DNS CName of www to www.myapp.com.herokudns.com
- Heroku DNS added www.myapp.com
In Setup Heroku and GoDaddy? allegutta solves the issue by masking the heroku-app-name domain with the .com domain. Instead of slooob.com.herokudns.com, use your original heroku app url ([heroku-app].herokuapp.com) and it should work. Just worked for me.
