You can connect to your server using the IP address and port that were emailed to you when you purchased your server (or by using a domain/subdomain you may have set up already). Your IP/port should be entered the same way you'd enter in an IP you would for any public network. If you have never used a port, please note that it should be added to the "Port" field in the Minecraft client.
If you cannot find an email from us, please be sure your email address is correct on your account and be sure to check your spam/junk folder.
If your email address is correct and you still cannot locate any emails from us, please contact our Billing team so we can better assist you.
If you have not yet purchased a server, you will need to do so before any service will be provisioned. Please note that IP addresses can only be assigned post-purchase. Therefore, we cannot provide you with an IP before you have a server.
