Multiple SSH keys - invalid ssh key expired

When I try to log into the IP address 35.192.33.20 -> works https://http://35.192.33.20/ -> doesn't work

The logs show an invalid ssh key error.

So, I ran this command on my gcp compute engine and it shows multiple ssh keys.

ls .ssh开发者_StackOverflow

The result showed multiple keys

google_compute_engine google_compute_engine.pub google_compute_known_hosts home home.pub id_ed25519 id_ed25519.pub ssh-key-dec6 ssh-key-dec6.pub ssh-key-v1 ssh-key-v1.pub

I am hoping to connect to the server using ssh. Can anyone help me delete so many of these ssh keys?
