golang x509 cannot validate certificate for 1

This error message indicates that the x509 certificate validation process failed for a specific certificate identified by the number 1. There can be a variety of reasons why this error occurs, but some common causes include:

1. The certificate is expired or has been revoked, and therefore cannot be trusted.
2. The certificate was issued by an untrusted or unknown Certificate Authority (CA).
3. The certificate does not match the hostname or IP address of the server or service being accessed.
4. The certificate chain is incomplete or incorrectly configured, causing the validation process to fail.

To resolve this error, you may need to obtain a new certificate, verify that the certificate was issued by a trusted CA, ensure that the certificate matches the server or service being accessed, or correct any issues with the certificate chain. Additionally, you may need to update your application or system to ensure that it is using the correct certificate and configuration settings
