Join problems with servers in Minecraft what to do?

Today I downloed Minecraft and of course I wanted to play on a server. The problem is that every time an error message appears, I have also added pictures of it

I play the latest Java version and have entered everything correctly (i.e. Server and so on)

Does anyone have any advice on how to fix this

I assume you bought & downloaded the original? Then it could be due to your network or you entered the IP incorrectly. You can see if you can't reach other servers either.

If you have downloaded a "cracked" version, you will not be able to join on official servers.

If you want to play grief games you need the 1.8
