I am trying to remote ssh into Raspberry Pi (latest operating system with all upgrades). I am getting the following error
failed: Error: No route to host
Note: I am able to successfully remote SSH from Mac terminal.
SSH from VS code terminal is failing too.
ssh Lily@Lilac.local
ssh: connect to host lilac.local port 22: Undefined error: 0

I tried downgrading VSCode and the SSH Remote plugin based on the net research. Reinstalled Raspberry Pi operating system and set up SSH.
Additionally VS Code terminal :
ssh Lily@Lilac.local -v
OpenSSH_9.8p1, LibreSSL 3.3.6

If you are on Mac (Sequoia), see this answer.
TL;DR:
