Minecraft multiplayer doesn't work, what should I do or where are the settings?

Minecraft multiplayer doesn't work, what should I do or where are the settings?

Causes:

Do you have a cracked game? → you can only join on servers that allow cracked players in the settings

Do you play the Bedrock version? → you can only join on bedrock server, not java edition server

Do you play console versions like xbox, ds, etc? → You can only join a server from the console, not bedrock server, not java server

Is your pc connected to the internet?

Are you logged in to Mojang or Minecraft acoount?
