Apache doesn't work on port diffrent than standart on Centos 7/OpenVZ container

I tried to change the default Apache port on the Centos 7 OpenVZ container, but it just didn't work. curl **.**.**.**:8080 curl: (7) Failed to connect to **.**.**.** port 8080: No route to host But it works correctly with the standard port: $ curl -I **.**.**.** HTTP/1.1 403 Forbidden Date: Wed, 01 May 2019 01:06:31 GMT Server: Apache/2.4.6 (CentOS) Last-Modified: Thu, 16 Oct 2014 13:20:58 GMT ETag: "1321-5058a1e728280" Accept-Ranges: bytes Content-Length: 4897 Content-Type: text/html; charset=UTF-8 At first I thought it was related to the SELinux policy, but as I read further, SELinux does not work on OpenVZ - Openvz_SELinux . When I tried to change the port to Centos 7 KVM VM, it worked flawlessly (the necessary rules were created for SELinux): $ curl -I **.**.**.**:8080 HTTP/1.1 403 Forbidden Date: Wed, 01 May 2019 01:09:51 GMT Server: Apache/2.4.6 (CentOS) Last-Modified: Thu, 16 Oct 2014 13:20:58 GMT ETag: "1321-5058a1e728280" Accept-Ranges: bytes Content-Length: 4897 Content-Type: text/html; charset=UTF-8 After that I changed the OS on the OpenVZ container to Ubuntu 18.04. It works correctly. $ curl -I **.**.**.**:8080 HTTP/1.1 200 OK Date: Wed, 01 May 2019 01:19:57 GMT Server: Apache/2.4.29 (Ubuntu) Last-Modified: Fri, 12 Apr 2019 08:09:12 GMT ETag: "2aa6-58650d16807ed" Accept-Ranges: bytes Content-Length: 10918 Vary: Accept-Encoding Content-Type: text/html Any suggestions on this case? P.S. Firewalld, iptables and ufw are disabled on all VPS.
