SSH kann aufgrund eines Authentifizierungsproblems nicht ausgeführt werden

Ich kann jetzt aufgrund von Authentifizierungsproblemen keine SSH-Verbindung zu meinem API-Server herstellen. Früher musste er sich anmelden, ohne ein Passwort zu fragen. Ich habe mit ssh-copy-id versucht, den öffentlichen Schlüssel vor dem Ausführen von ssh auf den Server zu kopieren, was jedoch ebenfalls fehlschlägt, da er erneut nach dem Kennwort für die Anmeldung fragt.

Befehlsausführung: ssh -vvv -i /Users/mrinmaykalita/.ssh/id_rsa 173. *. . **

Ausgabe:
