Minecraft servers not working?

Hey so I play minecraft Java but whenever I want to join a server it says connection failed not authenticated with Minecraft.net I have definitely tried over 20 servers and the only one that works is BlockDrop Network but I honestly like the server not so because of that someone knows what I can do to get on the other servers?

Check the internet connection to your device

Delete Minecraft and download it again

This is a known bug.

Try logging out of the launcher and logging back in again. That always worked for me.
