Couldnt start my ATM-10 Minecraft Server, looked at the Startup Menu → Neoforge Version 21.10.49 (Before when setting up the Server it was Version 21.1.211)
First try stopping+starting the MC instance and re-selecting the version. NeoForge has had some issues with their maven lately, which may have buggered with the version selection somewhat.
Then if that doesn’t work: stop the MC instance via the main web panel, click he MC instance’s folder icon, delete the NeoForgeVersionManifest.xml file, then start the MC instance again.
