현재 저는 Windows 11에 docker desktop을 사용하고 있습니다.

docker desktop에서 로그인도 잘 되어 있습니다.

해결책

어떠한 원인인지 모르지만 docker desktop에서는 로그인이 되어 있지만 docker hub에는 로그인이 풀려있는 것으로 보입니다.

그래서 콘솔에서 다시 로그인을 진행합니다.

D:\Workspace\Postgres\Dockerfile>docker login
Authenticating with existing credentials...
Login Succeeded

Logging in with your password grants your terminal complete access to your account.
For better security, log in with a limited-privilege personal access token. Learn more at https://docs.docker.com/go/access-tokens/

로그인이 다시 되는 것을 볼 수 있습니다.

push도 다시 정상적으로 동작합니다!
