I am running a discord bot that requires voice commands in my Raspberry Pi 4, and installed OpenJDK 17.0.1 on it. I also used pyenv to install python 3.10 on the Pi, and set the version to be global. I've installed lavalink.jar as well. Lavalink runs fine, it's that the python script, which uses wavelink, cannot connect to the lavalink server. I have also installed ufw and ran sudo ufw allow <my port number>, yet it still does not work. How can I fix this?

Here is my application.yml file

      # - "dzisrc:%ISRC%" # Deezer ISRC provider
      # - "dzsearch:%QUERY%" # Deezer search provider

After some digging, I have used the netstat -t -l -n command and got this result:

Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State
tcp        0      0 *               LISTEN

tcp6       0      0 :::8080                 :::*                    LISTEN
tcp6       0      0 :::22                   :::*                    LISTEN
tcp6       0      0 ::1:631                 :::*                    LISTEN

This was run while the lavalink server was running. I presume that this means that the lavalink server is not recognized by the Raspberry Pi, so how would I make my Pi recognize the server?

After asking around, I have found the answer to my problem.

I wasn't calling Lavalink from its directory (instead calling it from somewhere else), causing it to default to port 8080 (as seen in the netstat -t -l -n command), and use a different password than the one I set in the application.yml file, causing it to be unreachable by my python program.
