| Reason | Explanation | |--------|-------------| | Outdated API | The addon was built for an older version of Meteor that is no longer compatible. | | Mismatched Minecraft version | Addon uses a different MC version (e.g., 1.19.2 addon on 1.20.4 Meteor). | | Missing meteor-addon.json | The JAR doesn’t properly declare itself as a Meteor addon. | | Corrupted JAR | The file was partially downloaded or modified. | | Signature / developer check | Meteor may reject unsigned or untrusted addons (depending on settings). | | Duplicate or conflicting addon | Another addon with the same internal ID is already loaded. | Example post:
