Following Till (Your server is a vserver, so you can not configure the network from within the virtual machine. The network is configured on the host server.
), I added IPv4 18.104.22.168 on host server:
Login Proxmox -> Datacenter -> My Dedicated Server (0.0.0.0) -> My OpenVZ VM (22.214.171.124) -> Network -> Add -> IP address (venet) -> IP address: 126.96.36.199 -> Add
Now, http and https are OK (SSL self-signed, at the moment).
