Note that OpenSSH 7.6p1 does not support OpenSSL 1.1 so this must be a
vendor modified version, which might or might not make a difference.

some of your keys are in an ssh-agent, including the "jumpline" one
that the server later accepts.

this time the key is not available in an agent.

I'd guess that the reason it doesn't work is that the key is encrypted
and neither the agent nor a tty to ask for the decryption passphrase
is available.  Try repeating your command line test after unsetting
SSH_AUTH_SOCK (which will prevent ssh from knowing how to talk to the
agent).

    Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
