Where did you get this IP? Are you using your home pc as a server & using your ISP static IP to configure your VPS?
These addresses are in use by many millions of independently operated networks, which might be as small as a single computer connected to a home gateway, and are automatically configured in hundreds of millions of devices. They are only intended for use within a private context and traffic that needs to cross the Internet will need to use a different, unique address.
Configure the IP address you get from the VPS provider into your DNS settings.
