Headless server could not resolve multiplayer.factorio.com

Post by DanielJay »

I have a VM running Factorio and it has been running fairly smoothly. Looking at my status of the running game I am noticing the following frequently in the output of systemctl status factorio.

Code: Select all

However if I check for access to the URL it pulls up just fine.

Code: Select all

user@host:~$ nslookup multiplayer.factorio.com
Server:         10.x.x.1
Address:        10.x.x.1#53

Non-authoritative answer:
multiplayer.factorio.com        canonical name = arcane-frog-e4ehwzpn8h88wd5p7lo6bqrt.herokudns.com.
Name:   arcane-frog-e4ehwzpn8h88wd5p7lo6bqrt.herokudns.com
Address: 23.22.5.68
Name:   arcane-frog-e4ehwzpn8h88wd5p7lo6bqrt.herokudns.com
Address: 52.21.227.162
Name:   arcane-frog-e4ehwzpn8h88wd5p7lo6bqrt.herokudns.com
Address: 54.237.159.171
Name:   arcane-frog-e4ehwzpn8h88wd5p7lo6bqrt.herokudns.com
Address: 3.226.182.14
And if I run curl to check for connectivity I get:

Code: Select all

user@host:~$ curl multiplayer.factorio.com
<!doctype html>
<html lang=en>
<title>Redirecting...</title>
<h1>Redirecting...</h1>
<p>You should be redirected automatically to the target URL: <a href="https://multiplayer.factorio.com/">https://multiplayer.factorio.com/</a>. If not, click the link.
I am running pfsense as my firewall and have all of the Factorio.com URL and this same herokudns.com domain whitelisted in my machine with no outgoing filtering going on.

Is this anything to worry about? Any possible resolution to fixing this?
