comment SSH with PAM Google
From your log file I see several problems: 1. error: Could not load host key: /etc/ssh/ssh_host_ed25519_key is the key there? Do you need this key (else remove it from sshd_config). 2. (pam_google_authenticator)[358]: Invalid verification code and 3. error: PAM: Cannot make/remove an entry for the specified session for nonadmin from 162.17.78.154. Please ort out this problems one after another, starting with the missing server key.

Have you checked the times on your server and client devices? Google authenticator only works fine if the times are in sync.
