Servers not starting

I’m super new to linux, so please try to explain it to me like I’m 5.

I’m running it on Ubuntu server 20.04, I followed the tutorial pretty closely I think but theres this part Im stuck at.

When I click start on my server through the webui, it just doenst do anything.
Heres a few lines of the log, it says this everytime I press start and nothing else:

{“level”:“info”,“message”:“[gaggle] issued command : "start"”,“timestamp”:“2023-03-07T07:18:13.015Z”}
{“level”:“info”,“message”:“[gaggle] received request "start"”,“timestamp”:“2023-03-07T07:18:13.016Z”}
{“level”:“info”,“message”:“[gaggle] issued command : "start"”,“timestamp”:“2023-03-07T07:18:23.543Z”}
{“level”:“info”,“message”:“[gaggle] received request "start"”,“timestamp”:“2023-03-07T07:18:23.545Z”}

Can anyone here help me with this? I just don’t really know where else to go from here. The server doesn’t even do anything in response, it just stays offline all the time.

What version of MC are you trying to start?
What version of Java are you using?

What version Java does your MC version require?

Ohhh, I’m using 1.19.3.

I forgot to get java 19, thanks for reminding me lol
