Why can't NodeJS (request) make a request to a local resource by domain?

Question

Debian

There is a server machine on Debian 8.6 x64.
Literally yesterday they installed it, everything was set up, it costs ISPManager, Apache2 (: 8080) + Nginx (: 80), NodeJS (v4.6.2, but I tried different ones, from 0.12 to 7.1). For requests, the Request
package is used . Request via domain:

request('https://my-domain.ru/rest/request', callback());

Mistake:

[Error: getaddrinfo ENOTFOUND my-domain.ru my-domain.ru:443]
  code: 'ENOTFOUND',
  errno: 'ENOTFOUND',
  syscall: 'getaddrinfo',
  hostname: 'my-domain.ru',
  host: 'my-domain.ru',
  port: 443 }

The request is made via IP:
request('http://175.90.1.55', callback());
In this case, the request goes through.
Do not pay attention to protocols, it is not critical.
The bottom line is that my-domain.ru opens on IP 175.90.1.55, although there are a lot of other resources on the server.
If necessary, I can attach Apache and Nginx configs.
The problem is solved if you write 175.90.1.55 my-domain.ru in / etc /hosts , but this is not the correct solution, since there are still a lot of other resources on the server. Nginx config:

server {

Answer 1

Tell me, do you get the desired result using https://my-domain.ru/rest/request through a browser?
I don't want to offend anyone, with such a set of tools you look like a knowledgeable person, but is the virtual host my-domain.ru exactly configured correctly? ;-)
