How to set up a Linux Valheim dedicated server:

Use my referral link if you do not already have a DigitalOcean Account, gives me free credit on my account, if not no biggie! https://m.do.co/c/9d2217a2725c

Use my code and you get $100 in credit over 60 days. (good way to test your dedicated server)

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

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
systemctl status valheimserver.service
reboot

ENJOY!!!
