Answer 1

The error indicates a problem with SSL certificate validation, the SSL certificate used by your application was not recognized as valid because it was signed by an untrusted certificate authority (CA). To resolve this issue, you need to manually add the self-signed certificate to the Trusted Root Certification Authorities store on the local computer.
