Tmux with Bungee Cord

I have re-written my scripts to start my BungeeCord server to utilize tmux. I'm having an issue sending the shutdown command to Bungee to do a graceful shutdown. Anyone got any ideas.

I use a similar script to start my Spigot servers, and they have no issues.

I did some testing and replaced the bash -c "${MC_TMUX_SEND} 'end' C-m", with bash -c "${MC_TMUX_SEND} 'send' C-m" and I get response from the console.

The only thing I can think the issue is using end.

I have attached my scripts...
