I have followed the instructions to create a Forge Server, which runs, on 1.15.2.
I have followed the instructions to mod my client game, on 1.15.2, and have tested the mods to ensure they all work, which they do.
I have followed the instructions to add mods to the server, making sure that both the server's mod files and my client's mod files are the exact same files.
Yet the server does not load up with the mods.
Single player works just fine, but when I switch to multiplayer and connect to my server, it's just vanilla. As though nothing I did all morning existed.
I do not get error messages.
I am at a loss for how to correct this.
What further information is needed to help me, and where do I locate it?
