Minecraft balena server not working

Hi,
I’ve recently used this tutorial: https://www.balena.io/blog/how-to-create-a-minecraft-server-for-the-pi-4-with-balena/ to create a minecraft server on my raspberry pi 4 with 2gb of ram, however i can’t connect to it and get the below error:

this is my output from the balena dashboard that i think is related to the problem

Hi

Are you setting this up for playing over the local network?

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

Hi,

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?

Thanks

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.
