Masterhost + Heroku?

Question

Domain name market

The story is this, I have:
- .com domain on the masterhost
- project on heroku
I need a project on heroku to open on my domain.
I read two manuals:
devcenter.heroku.com/articles/custom-domains
masterhost.ru/support/doc/dns-editor/
It didn't help me. I read other materials on Habré, but it did not help either.
The control panel now looks like this:

With these settings, the site simply does not open.

Answer 1

You need to create an untitled A-record and point it to the IP given in heroku.
That is, in the entry with the name heroku2, delete the name.
For www to work too, you need to create a record called www, type CNAME, and point it to your domain name without www.
After that, wait for the DNS to populate and check that ping <your domain> is getting responses from heroku's IP.
If it doesn't work after that, then something is wrong with heroku.

Answer 2

Where the record
is heroku IN CNAME surgenov.herokuapp.com.
should be replaced with
@ IN CNAME surganov.herokuapp.com.
or on
surganov.com. (end dot required) IN CNAME surgenov.herokuapp.com.
Then you need to add either
www (without dots) IN CNAME surgenov.herokuapp.com. ,
so that the domain with www is also opened, or
* IN CNAME surgenov.herokuapp.com.
so that all subdomains point to Heroku (except those described separately).
You can immediately check the changes in a couple of minutes with this query
dig @ns.masterhost.ru surganov.com
In order not to wait until the DNS is updated, or Windows nslookup, the server parameter is specified by the master host. Well, or ask someone to check right here, how will you do
at the moment your domain is configured for several masterhost IPs, and heroku.surgenov.com domain points to heroku
