Diagnose Why You Can't Join an Older Server

Verify Plugin Installation

The most common reason for connection failure is that Via Version Plugin isn't actually installed on the server. Contact your server administrator and ask them to confirm the plugin is loaded. They can check their server's plugin folder or use server commands to verify.

Check Version Direction

Via Version Plugin only works when your client is newer than the server. If you're trying to join a server running a newer version than your client, this plugin won't help—you need to update your game instead.

Test Basic Connectivity

1. Verify the server address is correct and the server is online

2. Try connecting with a vanilla launcher (no mods) to rule out other mod conflicts

3. Check your firewall and network settings aren't blocking the connection

4.

Report Persistent Issues

If you've confirmed the plugin is installed and the version direction is correct but still can't join, provide your server administrator with the exact error message you receive. This helps them diagnose whether it's a plugin configuration issue or a deeper compatibility problem.
