Servers bug

Hi there, I just started minecraft bedrock on my PS4 and then I went to icon servers And I was confused after then I saw all servers example: HIVE, Lifeboat and much more. I press join and I was there, but after 20 seconds (maybe 15s) I got an error, that means my minecraft closed. When I start Minecraft again there weren't servers. When are the servers releasing? Please try to fix that.
