Velocity Proxy
- Version: 3.4.0+
- Install the plugin only on Velocity if Velocity is present.
- This plugin in the backend server won't operate when using Velocity
Client Requirements
- Minecraft client 1.20.5 or newer: Mojang changed the handshake and encryption flow in 1.20.5. Older clients cannot complete the encryption sequence. This plugin will not send encrypted request packet to players with older versions.
