Redirect domain to an app hosted on Heroku

Question

I have a website hosted on Heroku. (let's say : my-app.herokuapp.com)

I bought a domain name on OVH. (let's say : my-domain.com)

I added my-domain.com to domain list on Heroku.

In DNS target, I have my-domain.com.herokudns.com .

I have to supply this to my DNS provider for the destination of CNAME or ALIAS record. I did so on OVH. I added :

Subdomain : www.my-domain.com

TTL: By default

Target : my-domain.com.herokudns.com. .

But nothing works, I must be missing something. I'm still a beginner with this DNS thing. In my browser, I have DNS_PROBE_FINISHED_NXDOMAIN or ERR_NAME_NOT_RESOLVED error when I'm trying to access my-domain.com.

It's my first website I'm trying to finish and I will be so happy if somebody can help me. Thanks in advance !

Answer 1

You said you created a record for www.my-domain.com, but then you are trying to access my-domain.com, which is a different hostname. You need to create an ALIAS record for it as well.
