Help!

I need help with BungeeCord! I don't know if I did the set up wrong, but I can't seem too be able to connect to the bungee server it's self.

Here is the config. By the way, these servers are hosted.

groups:
md_5:
- admin
disabled_commands:
- disabledcommandhere
player_limit: -1
stats: 6732c149-ef53-434d-8fc5-9e242e920f7c
permissions:
default:
- bungeecord.command.server
- bungeecord.command.list
admin:
- bungeecord.command.alert
- bungeecord.command.end
-...

Help!
