When this happens it means we are currently whitelisted. This means only a select few can come online, as we are updating things. This would happen if maintence is needed, or now, as we are getting things set up.

This is a very rare problem, however if this ever occurs, the problem is probably in your settings. Press the "esc" button then click options. Once there, click Controls and make sure everythign is assigned to the right keys. If everything is normal there, click Done and click on Chat Settings. Chat should be on Shown and Colors should be on. If everything is fine there, exit minecraft and open up the launcher and log in again.

This happens when you are on a version of Minecraft that the server does not support. As of now the server only supports 1.12, so when playing ToonTownCraft, make sure you are on 1.12.
