Configure HideMyAss VPN on dedicated server

Hello, I have Linux-based dedicated server and I wonder if someone could install HideMyAss VPN service on that server. Later, this server will be used as a socks5 proxy tunnel, so it's purpose is to change server's original IP address to the one of HideMyAss VPN server IP. In other words, this command executed on server: wget -qO- [login to view URL] Should return the IP address of HideMyAss VPN server. Current OS on the server is Ubuntu 16.04, but if needed it can be reinstalled to any other popular Linux distribution. I am not very experienced at server administration, but I have tried to follow these instructions: [login to view URL] But VPN service does not work, I got this error so far: Calling OpenVPN as process... Connecting to " USA, Texas, Dallas [login to view URL] " (tcp/443) Enter CTRL-C to terminate connection Waiting for connection to complete... Option 'explicit-exit-notify' in [PUSH-OPTIONS]:5 is ignored by previous <connection> blocks Option 'explicit-exit-notify' in [PUSH-OPTIONS]:11 is ignored by previous <connection> blocks do_ifconfig, tt->did_ifconfig_ipv6_setup=1 RTNETLINK answers: Permission denied Linux ip -6 addr add failed: external program exited with error status: 2 I have also disabled ipv6, but it didn't help. I think for experienced Linux admin it would take few minutes to fix it and for me it would take few days or so ;) If you can help me - please make a proposal and I will send you root SSH logins to the server and HMA login information, so you could fix this problem remotely. Thank you in advance! :)
