Frequently asked questions
How do I check if ViaVersion is actually working?
Join your server from a client version newer than the server's native version and run /viaver list; if your name appears with the newer version shown, it's working. If you can't connect at all, the plugin likely isn't loaded or your client is too new for the current build.
Why can't my friend on an older version join my server?
ViaVersion only lets newer clients join older servers, not the reverse. To allow older clients you need to install ViaBackwards, and for very old versions also ViaRewind, alongside ViaVersion.
Do I need ViaVersion on my BungeeCord proxy or on the backend servers?
Install ViaVersion on the proxy itself, not on the backend servers behind it. Putting it on both can cause double protocol conversion and break connections.
What does /viaver list actually show me?
It lists every online player alongside the client version they're connecting with. This is the fastest way to confirm who is on which version and whether protocol translation is happening.
