I can't deliver any messages on discord and I wanted to connect my new account to my Minecraft account

did it say you have to wait 10 minutes before you can send messages on this server?

everyone has to wait 10 minutes to be able to speak incase it is an alt or something then staff can ban them

 There is no discord to minecraft account connection. You can speak there without verification. The discord-to-dmu bot may be down sometimes however
