Bought a domain on the site (netim.com)
Uploaded the application to Heroku
Added site.ee domains
www.site.ee to the
Heroku application settings Default site.ee
DNS settings.
NS a.ns.netim.net.
site.ee. NS b.ns.netim.net.

read, tried.
When editing NS servers on the registrar's site, I cannot specify the IP address, only NS.
I take the NS registrar server.
I set up DNS, delete everything that is there and add two A records with IP as in the
site.ee article. A 75.101.145.87
www.site.ee. A 75.101.145.87
And nothing happens. Everyone uses those pieces 4 that are under the heroku itself. At the same time, the error Your DNS setting above produced the following error (thus the domain name is not online): not loaded due to errors
appears in the administration panel . Apparently it was not necessary to bang all the settings. After restoring the settings of the registrar, I encountered such a problem by filling in the fields Address www IP address 75.101.145.78 added add @ does not work, it gives an error Bad parameters [subdomain] - The parameter syntax is wrongA75.101.145.87
added * and with puts field Address
Deleted default settings A
site.ee. NS a.ns.netim.net.
site.ee. NS b.ns.netim.net.
site.ee. MX(10) mxv1.spamora.net.
site.ee. MX(10) mxp1.spamora.net.
site.ee. MX(10) mxl1.spamora.net.
site.ee. A 75.101.145.87
*.site.ee. A 75.101.145.87
www.site.ee. A 75.101.145.87
The result did not work
Article #2
Default NS registrar servers
add CNAME with existing A, the same is not obtained

with default
site.ee. A 185.26.106.241
www.site.ee. A 185.26.106.241
add www and '' does not work, I get an error
Bad parameters [subdomain] - A DNS record of type A or CNAME already exists for this subdomainCNAMEheroku.com
Removed the default ones and added 2
site.ee CNAME records. NS a.ns.netim.net.
site.ee. NS b.ns.netim.net.
site.ee. MX(10) mxv1.spamora.net.
site.ee. MX(10) mxp1.spamora.net.
site.ee. MX(10) mxl1.spamora.net.
site.ee. CNAME heroku.com.
www.site.ee. CNAME heroku.com.
Zero point
Article #3
deleting the A record from the default settings
to add a record with @(@ A 174.129.212.2 ) does not work, gives out
Bad parameters [subdomain] - The parameter syntax is wrongA75.101.145.87
Added 3 A records with the parameter *
site.ee. NS a.ns.netim.net.
site.ee. NS b.ns.netim.net.
site.ee. MX(10) mxv1.spamora.net.
site.ee. MX(10) mxp1.spamora.net.
site.ee. MX(10) mxl1.spamora.net.
*.site.ee. A 75.101.145.87
*.site.ee. A 75.101.163.44
*.site.ee. A 174.129.212.2
and a CNAME entry

didn't help either.
Apparently I'm new to this. Ask for help from more experienced people.

Answer 1

It shouldn't work for you. Specifying an A record for clouds is somehow wrong.
And to check use dig or nslookup
