First, make sure that Nate Bot is online and running as expected:
When there is a Green Dot and the Box shows "Online". It means Nate Bot is online.
If Nate Bot is indeed offline, there are two places you can check the Status of Nate Bot:
Our Discord Server (Best Place)
If we are aware that Nate Bot is down, you shouldn't be able to send messages or anywhere and there should be a Status message that is sent in our #status channel.
