For some reason, I am unable to access our website www.doccaster.com (Bad request nginx). We are hosted on amazon EC2 with elastic IP associated to it. The weird part is

  1. I can access it through the public dns url http://ec2-184-73-195-180.compute-1.amazonaws.com
  2. My co founder who is located in another city can access it via www.doccaster.com.

I observed that my instance was failing reachability check, so I launched a new one and assigned it the the elastic IP. I tried to ping the IP address from my machine but no success. Any help will be really appreciated.

More details I ran the following command on my server

netstat -lntp | grep -E 'apache|httpd'

and it displays


for httpd . Is this accurate ? Should it be 0:0:0:80? or does it not matter?


The problem is you have set the wrong IP address in the DNS.

error@underground ~ $ host www.doccaster.com
www.doccaster.com has address
error@underground ~ $ host doccaster.com
doccaster.com has address

Once you fix this, you should find things start working.
