Auto Reconnect
This is an updated version of the Bungee-Reconnect plugin that works on higher Minecraft versions.
Original plugin link: https://www.spigotmc.org/resources/bungee-reconnect.16429/

NOTICE: I have noticed that the plugin is struggling to reconnect players to more modern servers, and the player ends up stuck in limbo. Currently, the only way to avoid this is to increase "delay-before-trying" to make sure the server is fully started and ready for players before the plugin attempts to connect. I have some ideas on how this can be resolved, however.

A simple BungeeCord-Plugin that automatically tries to reconnect all players whenever a server restarts.

Features:

• Reconnect all players when a server restarts - you don't need an additional limbo server.
• Move the affected players to the fallback server or kick them from the proxy, if the server doesn't start within a specific time period again.
• Send titles and action bar messages (+ animated dots variable) to the players while they're waiting for the reconnect or if they got moved to the fallback server.
• Configure servers that are to be ignored by this plugin, custom messages, the maximum amount of retries and many other things!
• Compatible with other BungeeCord plugins - its behavior isn't supposed to break anything at all!
• Provides an API for plugin developers.

API:
Auto-Reconnect provides a ServerReconnectEvent. If you're a developer and want to cancel the reconnect-process for any reason, you can just cancel this event.

Data Collection: This plugin utilizes bStats for plugin metrics. bStats does not collect any personal data. Most of the collected data is information about the plugin's server like player count, online mode, Minecraft version, Java version, and more. All data gets sent and stored completely anonymously. Server IPs are only stored for ratelimiting and not linked to the data. All data that is collected is publicly visible. If you are interested in what data is collected for your Minecraft server, take a look at the pages for the plugins on your server. Please note that plugin authors can also send data that is customized for their plugin. If you don't want bStats to collect data from your server, you can disable it in the bStats config file. This file can be found in the /plugins/bStats/ folder. More information is available here
