This error message usually occurs when there is an issue with the SSL/TLS certificate chain. It means that the SSL/TLS certificate presented by the server could not be verified by the client because the client cannot find a valid certification path to the certificate authority (CA) that issued the certificate.
There are a few possible reasons why this error may occur:
1. The SSL/TLS certificate installed on the server may be expired or invalid.
2. The SSL/TLS certificate may be self-signed or issued by an untrusted CA.
3. The client may not have the necessary intermediate CA certificates installed.
4. The client may be using an outdated version of Java or other software that does not support the SSL/TLS certificate.
To resolve this issue, you can try the following:
1. Check the SSL/TLS certificate installed on the server and ensure that it is valid and issued by a trusted CA.
2. Install the necessary intermediate CA certificates on the client.
3. Update the client software to the latest version that supports the SSL/TLS certificate.
If none of these solutions work, you may need to contact your system administrator or the website owner for further assistance.
