When I try to log in to Vault using the CLI:
vault login ${MY_SUPER_SECRET_TOKEN}
I get the error: Error authenticating: empty response from lookup-self
I am able to log in via the UI using a Token or OIDC.
vault read auth/token/lookup-self looks OK.
Setup is the same as other Vault setups that are CLI-working but I can't seem to pin down where the error is in this one.
