Firstly, you will be needing to download the software WinSCP as that is the most recommended SFTP client to connect with your SFTP configuration (but you can always use any other SFTP client that also works)! Once you have opened the software, you will be needing to choose the SFTP method for logging in and then back to the game panel SFTP configuration page. You then will copy the information to your client and the password would be the same as your control-panel's account.

When logged in to your server's SFTP, you will be able to upload folders & premade servers without any issues!

First, get a domain from somewhere (any active registrars), if you want a free domain, get it from Freenom.com. Second, create a Cloudflare account and set your domains nameservers to whatever Cloudflare tells you to. Wait until nameservers are verified, and then go to the DNS tab of your domain on Cloudflare, and create an SRV record with whatever you want for name, set service to _minecraft , Set Priority to 5, Weight to 0, Port to the MC server port shown on your server page, and target to the domain of the node you are on, aka if you are on Redstone servers, put the target as redstone.mythicalnodes.xyz. Third, make sure to click save, make sure your mc server is on, and then test out your new custom domain to see if it works (note, this custom domain tutorial only works for Java edition MC servers)

Go to File Manager via control panel, locate server.jar and delete it. Then go to the console tab, start the server and choose what version you would like your server to be.

Start by going to your game control panel and login with your details from the dashboard. Then click on the server that you want to access your console with and you will be able to send commands and more! Make sure you do not try sending a command with a / otherwise the command will not run and will say it is unknown.

Once you setup your server, go to your game control panel and click on the server you want to get the address of. Then you will be able to see the statistics of your server where it says under your server's name, here's a examples of a picture:

Below where it says your subdomain address, you can click on it and it will automatically copy it for you. It should look like this: yourserver.mythicalnodes.xyz:25565 as a example. Then you will be able to join in-game.
