How to set up a Linux Valheim dedicated server:

Start your own dedicated Valheim server built on Ubuntu with DigitalOcean services: * https://m.do.co/c/9d2217a2725c *

If you use my referral link, you will get 100USD credit for 60 days. (good way to test your dedicated server)
I pay 40 bucks a month for my server.

Never run any script on a production server, unless you know what you are doing.

Create VM with minimum 2 CPUs and 4GB of ram. Otherwise server won't start.

*DigitalOcean private IP and routing fix for Valheim: *

edit 50-cloud-init.yaml

vi /etc/netplan/50-cloud-init.yaml

remove private IP address on eth0 (might be 10.10.something - do not remove your public IP the same one you use to SSH into the server or access it)

netplan apply

reboot

Please do not use the Hosting Company Command Line Interface if you can help it. Download putty and connect to your server via SSH. Download Putty here:https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html If you can connect to your Server's Ubuntu install via SSH through PUTTY, your networking/security groups are most likely setup correctly (for port 22).
