Incorrect behavior of perform.login when switching between velocity servers

[seansolovev]

What behaviour is observed?

When a player switches from an auth server to another backend server that also has AuthMe installed, AuthMe on the destination server asks for the password again instead of recognizing the player as already authenticated.

AuthMe Velocity does NOT send perform.login to lobby when the player switches there. The Velocity log shows no authmevelocity output at all during the switch to lobby. AuthMe on lobby receives no login signal and kicks the player after the auth timeout.

Expected behaviour

Player switches from survival to lobby without being asked for a password again. AuthMe Velocity should send perform.login to lobby so the player is automatically authenticated.

To Reproduce

• Velocity proxy with AuthMe Velocity plugin
• survival — auth server (listed in authServers), AuthMe installed
• lobby — non-auth server (not in authServers), AuthMe installed

plugins/authmevelocity/config.yml:

authServers:
  - survival
allServersAreAuthServers: false
autoLogin: true
proxySharedSecret: "<same secret on all servers>"

AuthMe config.yml on every backend server:

Hooks:
  bungeecord: true
  proxySharedSecret: "<same secret as proxy>"

/config/paper-global.yml:

proxies:
  bungee-cord:
    online-mode: true
  proxy-protocol: false
  velocity:
    enabled: true
    online-mode: false
    secret: "<secret>"

Thanks for the quick decision! It really works but only with Dialog UI turned off

    # Requires an email provider to be configured to be useful.

    # The body text helps players understand what the dialog is asking them to do.
    showBody: true
    preJoin:
        # Show the login/register dialog during the Paper/Folia pre-join phase.
        # Independent from postJoin.enable; you may enable either or both options.
        # On non-Paper/Folia platforms this option has no effect.
        enable: false
        # Show a cancel button in Paper/Folia pre-join dialogs.
        # If disabled, players must submit the dialog or disconnect instead.
        showCancelButton: true
        # Allow closing Paper/Folia pre-join dialogs with Escape.
        # If disabled, the dialog stays open until it is submitted,
        # cancelled, or the timeout disconnects the player.
        allowCloseWithEscape: false
        # Kick players who cancel the Paper/Folia pre-join register dialog.
        # When false, cancelling lets the player join and shows a post-join register dialog instead.
        registerCancelKicks: false
        # Kick players who cancel the Paper/Folia pre-join login dialog.
        # When false, cancelling lets the player join in limbo to use /email recover.
        loginCancelKicks: true
    postJoin:
        # Show a graphical dialog UI for post-join login/register instead of chat messages.
        # Requires Minecraft 1.21.6+ on Spigot, or 1.21.11+ on Paper.

I've harden the check in 02ba9b5 , may not be the full fix we need, but it should help us to debug it effortlessly. Can you please try with the latest jenkins build and enable DEBUG logs ?
