I can't get into minecraft survival games?

Please can anyone tell me what i might be doing wrong. My friend and i got minecraft yesterday and we were so excited to start playing survival games but when i went into multiplayer and put in the ip address: us.mcgamer.net, it said that the server was outdated. Can anyone tell me what that means? My friend was able to get into it using the same exact ip address, and we got the exact same version of minecraft. Could it be something wrong with my computer or something? Is anyone else having the same problems?

Please make this best answer:

Your pc is full storage wise.

Delete atleast a gb of data.

We need to know your pc specs.

You're not doing anything wrong, it's a problem on their end. They probably haven't updated their server to work with the latest version of Minecraft yet.

When the launcher pops up for minecraft, click on " Edit Profile" and select an older version of the game. You might have to try a few different version before you get it right.
