As the title says:

I set up an Ark: Survival Evolved game server using Ubuntu 16.04. It is refusing to allow connections, even though the server is running and visible by Battlemetrics/ArkServers.net

External tools are showing the ports as closed. The ports are 7777, 7778, 27015, 27020. Netstat shows the Ark server using the UDP port 27015.

Things I’ve tried:

• Double checked the IPTables, UFW, and DigitalOceans web firewall.
• Disabled all of the aforementioned firewalls.
• Rebuilt the server multiple times. Validating successful installs/file downloads.
• Rebuilt the droplet, restarted the droplet, etc.

Anything I’m missing?
