Heroku app linking to domain providers website
<p>I'm in trouble.</p>

<p>I have this website which runs on heroku with a custom domain from another provider. I made the connection between the 2 with the correct DNS. </p>

<p>It seemed to work on my browser but it didn't work on other computers, and after clearing my cache it didn't work on mines either. When they visit the site it shows the domain providers website.</p>

<p>At first i thought it had something to do with ssl, cause i got errors saying your connection is not private. Then i changed <strong>config_force_ssl</strong> to false:</p>

<pre><code> # Force all access to the app over SSL, use Strict-Transport-Security, and use secure cookies.
  config.force_ssl = false
</code></pre>

<p>It seems that the A records in my domain providers DNS settings link to IP addresses and Heroku doesn't support ip addresses. Or it could still be something ssl related. </p>

<p>Here is my <strong>domain providers DNS</strong>:</p>

<pre><code>ftp.example.io - CNAME - example.io
www.example.io - CNAME - example-example.herokuapp.com
example.io - A - 91.184.0.100
localhost.example.io - A - 91.184.0.100
webmail.example.io - A - 91.184.0.100
*.example.io - A - 91.184.0.100
mail.example.io - A - 91.184.0.94
</code></pre>

<p><strong>Here is the domain i added on heroku</strong>:</p>

<pre><code>Domain name: example.io
DNS Target: example-example.herokuapp.com
</code></pre>

<p>I have no idea anymore about what it could be. Any help would be appreciated</p>
