I installed a modpack directly from forge, the server is set on the correct version and it appears I have enough resources to run the modpack. It works in singleplayer but stalls on startup when I try and launch the server with the modpack.
Reproduction Steps
Installed Forge Modpack
Attempted to launch server
Server begins loading but stalls on startup, RAM stays constant but CPU sitting at 0%

From the logs you shared, it looks like you’ve got some mods causing trouble for the dedicated server. Specifically, the “Oculus” mod is trying to load client-side classes (net/minecraft/client/gui/screens/Screen), and “Legendary Tooltips” is throwing initialization errors. These mods are likely client-only mods, which simply won’t work on a dedicated server.
Here’s your first step:
Check through the modpack and remove any client-only mods (like Oculus or anything similar) from the mods directory on the server. AMP should have a file manager for the Minecraft instance; dig in there and clear out the suspicious mods.
