I got it working ladies and gentlemen!
I created a folder a folder "locast2plex" in appdata
I customized the config data from the github and then copied it to the appdata/locast2plex folder
I removed all the paths and variables from the locast2plex docker container.
Then i added 1 path variable.
Container path: /app/config.ini
Host Path: /mnt/cache/appdata/locast2plex/config.ini
Access Mode: Read/Write
Description: Locast2Plex config.ini
*I had to set the Network type to Host
Came up with no issues.
