Can you tell the detailed steps that you did to get here? I am guessing you flashed the pi, the device came online, and this is what you saw - is that right? Did you run any other commands?
I’m trying to set it up for the local network - and have been messing around with it for about an hour trying to get it to work - i managed to fix the corrupt jarfile issue and get it to not come up with the error ‘could not connect’ but got stuck on this. I haven’t been able to access the server at any point throughout my debugging if that helps
I have tried setting up the server and I can confirm that I am able to see the message you shared but it looks like a warning to me, below that I can see the server starting successfully:

Can you check whether you can see that as well? Or share the whole log from the mc-server service if you do not mind.
Also, are you trying to connect using the balenaminecraftserver hostname to connect to the server? Could you try using the IP address to connect and see whether that works?
It seems to have started working when i turned on my pi this morning - i could successfully connect using the address balenaminecraftserver, which is weird because it wouldn’t work before. Thanks for your help and I’m sorry for any inconvenience caused.
I came here for a different balena project that was failing due to the same exception. I eventually found the solution and I thought I’d post it here in case anyone else needs it.
My project was running some java code over SSH on a balena device. The call the InetAddress.getLocalHost works fine when run directly, but fails over SSH.
