Who can tell what the problem is?

Answer 1

cURL error 7: Failed to connect to foods-service.com.ua port 443: Connection refused (see http://curl.haxx.se/libcurl/c/libcurl-errors.html)

Your host
1) was banned
2) your firewall is crookedly configured
3) outgoing connections are prohibited from the host.
For example, I'm fine

$ nmap -p80,443 foods-service.com.ua

Starting Nmap 7.12 ( https://nmap.org ) at 2017-02-05 22:24 CET
Nmap scan report for foods-service.com.ua (37.139.15.228)
Host is up (0.036s latency).
