What I did
This method looked slightly incomplete. If the port wasn't found, it'd return err, but that was always nil, so we'd print out :0.

Now, we construct a nice error message with the targeted port and the ones we found.

The --protocol flag is also now case-insensitive to prevent any weirdness/confusion there.

Fixes #10010.

This method looked slightly incomplete. If the port wasn't found,
it'd return `err`, but that was always `nil`, so we'd print out
`:0`.

Now, we construct a nice error message with the targeted port and
the ones we found.

The `--protocol` flag is also now case-insensitive to prevent any
weirdness/confusion there.
