Yeah, due to unknown reasons, the server likes to ban people for 5 minutes randomly.
Due to the fact threatening to DDOS the server is a serious matter, we have decided to leave the punishment until further notice. I hope you can...
Most chunks are generated. However, we are experiencing some form of RAM issues and TPS issues. We are looking for a fix. Sorry for any inconvenience.
I'm a bit late to replying, but just for anyone who cannot join the server (still), remove all capital letters from the IP and it might work.
