I kept skipping this step because the custom domain already showed up in my Heroku app. Ran this and it started working.
<pre><code>Heroku domains:add www.yourwebsite.com --app &lt;app name&gt;
</code></pre>
Bonus: Want every page to be secure SSL? Use this awesome NPM package <a href="https://www.npmjs.com/package/force-ssl-heroku" rel="nofollow noreferrer">https://www.npmjs.com/package/force-ssl-heroku</a>
<hr />
Update 2021: If you get a <code>sni_endpoint</code> error please refer here: <a href="https://stackoverflow.com/questions/70252737/heroku-custom-domain-sni-endpoint">Heroku Custom Domain: sni_endpoint?</a>

blocks|key|1278370|text|这对我起了作用，但我必须在命令的末尾包含--app+<app+name>。如下所示：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1278371|heroku+domains:add+www.yourwebsite.com+--app+<app+name>|code-block|syntax|javascript|1278372|对于应用程序名称，它是您在Heroku中创建应用程序时使用的应用程序名称。|1278373|entityMap^0|K|G|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@$9|P|A|Q|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|R|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|S|8|@]|D|@]|E|$]]|$1|M|3|-4|5|6|7|T|8|@]|D|@]|E|$]]]|N|$]]

This worked for me, but I had to include <code>--app &lt;app name&gt;</code> at end of the command. Like this:

<pre><code>heroku domains:add www.yourwebsite.com --app &lt;app name&gt;
</code></pre>

For the app name, it is the app name you used when creating the app in Heroku.

<pre><code>Heroku domains:add www.yourwebsite.com --app &lt;app name&gt; 
</code></pre>

This is the best way to do it as it needs to know which specific app to point to.

blocks|key|3647602|text|修好了！！在用Heroku应用程序设置了我的www域很长一段时间之后，我不得不将域指向Cloudflare，然后将其设置为：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3647603|1：https://i.stack.imgur.com/o6CJc.png。2：https://i.stack.imgur.com/P8PSQ.png。3：https://i.stack.imgur.com/BB0DI.png。|offset|length|3647604|然后一切只是完美地运作，非WWW域和WWW域。|3647605|我不需要进行任何URL转发，如下所示|3647606|4：https://i.stack.imgur.com/wgMit.png。|3647607|entityMap|0|LINK|mutability|MUTABLE|url|https://i.stack.imgur.com/o6CJc.png|1|https://i.stack.imgur.com/P8PSQ.png|2|https://i.stack.imgur.com/BB0DI.png|3|https://i.stack.imgur.com/wgMit.png^0|0|2|Z|0|14|Z|1|26|Z|2|0|0|0|2|Z|3|0^^$0|@$1|2|3|4|5|6|7|Z|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|10|8|@]|9|@$D|11|E|12|1|13]|$D|14|E|15|1|16]|$D|17|E|18|1|19]]|A|$]]|$1|F|3|G|5|6|7|1A|8|@]|9|@]|A|$]]|$1|H|3|I|5|6|7|1B|8|@]|9|@]|A|$]]|$1|J|3|K|5|6|7|1C|8|@]|9|@$D|1D|E|1E|1|1F]]|A|$]]|$1|L|3|-4|5|6|7|1G|8|@]|9|@]|A|$]]]|M|$N|$5|O|P|Q|A|$R|S]]|T|$5|O|P|Q|A|$R|U]]|V|$5|O|P|Q|A|$R|W]]|X|$5|O|P|Q|A|$R|Y]]]]

FIXED!! After struggling for a long time setting up my www domain with my Heroku app, I had to point the domain to Cloudflare then set it up as follows:
[1]: <a href="https://i.stack.imgur.com/o6CJc.png" rel="nofollow noreferrer">https://i.stack.imgur.com/o6CJc.png</a> .
[2]: <a href="https://i.stack.imgur.com/P8PSQ.png" rel="nofollow noreferrer">https://i.stack.imgur.com/P8PSQ.png</a> .
[3]: <a href="https://i.stack.imgur.com/BB0DI.png" rel="nofollow noreferrer">https://i.stack.imgur.com/BB0DI.png</a> .
Then everything just works perfectly both NON-WWW and WWW domains.
I did not need to do any URL forwarding as see bellow
[4]: <a href="https://i.stack.imgur.com/wgMit.png" rel="nofollow noreferrer">https://i.stack.imgur.com/wgMit.png</a> .

What is the correct way to connect a Heroku app with a custom domain?

This is how I did it in the past:

<ol>
<li>Point Godaddy's DNS to heroku's provided target (example:
<a href="https://peaceful-escarpment-22825.herokuapp.com" rel="noreferrer">https://peaceful-escarpment-22825.herokuapp.com</a>)</li>
<li>Turn on domain forwarding on the domain </li>
<li>Add domain to Heroku in the settings</li>
</ol>

For some reason now my provided target from Heroku is like this: mycustomdomain.com.herokudns.com. When I add that DNS to GoDaddy I get a There's nothing here, yet. page. 

Where am I going wrong? Thanks!
