Im not really sure where to post this in the first place, but ive been trying to set up a server on mc with a specific modpack without paying for one because ive set up modpack servers with relative ease in the past, and just following random threads sort of related to my issue is getting me nowhere... ive gotten everything set up like you would a normal server for 1.16.5 using java 8 and pasted a generic command into a batch file to start the forge jar, only after a few seconds the command prompt just says pause and prompts me to exit out and my server does not start... can i get help with this here?
