(22:58:35) | Loaded plugin Discord Team v1.1.5 by Owned​

I also created a new bot just for this plugin and restarted the server. When I restarted I got this message:

(22:56:34) | DiscordTeam was compiled successfully in 207ms
(22:56:34) | Unloaded plugin Discord Team v1.1.5 by Owned
(22:56:34) | [Discord Team] There is no Discord connection ... Please check your API key​

I confirm my bot is connected to my channel and the API key is correct. When I reload the plugin while the server is live It goes back to the first error.
