Docker Registry SSL Certificate Error: 'certificate has expired or is not yet valid'

This error occurs when the SSL certificate used by the Docker registry has either expired or is not yet valid. The current system time is checked against the expiration date of the SSL certificate to ensure that the connection is secure. In this case, the SSL certificate has an expiration date of February 22, 2023, which is in the future. However, the current system time is September 9, 2022, which is before the SSL certificate's expiration date. This means that the SSL certificate is not yet valid, and the connection cannot be established. To resolve this issue, you can check your system time and ensure that it is set correctly. If the system time is correct, you may need to contact the owner of the Docker registry or the SSL certificate provider to resolve the issue.
