    Hello,

    I have a non-CMM issue. I rented a VPS KWM server for storage purposes and running CentOS7 on it. Fresh install, nothing else. I need port 9000 to be open.

    I disabled SELinux, I opened port 9000, I restarted firewall and the server. And yet any connection from outside is refused. Like I am trying to put my backups to it but it refuses it.

    I don't know what else to do in this case. The port is listening, the port has an active service running, no SELinux, Firewall is active but port is open, and I also disabled Firewall for test purposes and it makes no difference.

    Maybe the guys around here have an idea?
