[SOLVED] Dedicated server stuck at "INF [DECO] write thread 3ms"

[Pyrotechnical]

(Solution: Turns out this means it is done lol. Wasn't able to connect because I had only allowed port 26900 through the firewall when I needed 26900-26905)

I had a singleplayer world on my Windows PC which I transferred to my Ubuntu 20 server and am trying to start a dedicated server with it, however, looking at the output log, it just gets stuck at "INF [DECO] write thread 3ms". The CPU usage is very low for all cores (4-6%), so I think it is just hanging. Here is the full output log, and here are the world settings:

 

<property name="GameWorld"						value="PREGEN10k"/>
<property name="WorldGenSeed"						value="asdf"/>
<property name="WorldGenSize"						value="6144"/>
<property name="GameName"						value="pregen"/>
<property name="GameMode"						value="GameModeSurvival"/>

 

Any ideas what I'm doing wrong? Thanks
