I'm currently creating my own Minecraft server network, and I want to know how to redirect a player from one server to another server when he clicks on a sign, for example.

My server is for 1.12.2.

The server must be in online mode.

On server 1, spigot is on server 2, sponge.

You should move from each server to the other server without joining again.

With bungee cord as far as I know you can connect servers to each other and then enter with a portal or with a comand

Yes, but Bungeecord only works in offline mode.

Sorry, I can't help you with that

Mi

Maybe a plugin

Al

I only know BungeeCord.

Why should the server be in online mode?
