Why isn't my Minecraft multiplayer not working?

I logged in didn't work, made new account didn't work, I can't load into any server. I even deleted the game and bought it agajn

Is your game PC or Xbox? If it's PC, try to connect to a network connection or get a more stable one. And then look up "minecraft multiplayer servers" on google and pick a server and press "add server" in the multiplayer minecraft menu and then put in the ip address and then you've got the server and can log on.
