    Connecting to the server may be unsafe due to SSL/TLS certificate validation issues. The server’s hostname or IP address does not match the certificate’s altnames. Read this KB article for instructions on how to fix this.

    You chose to ignore the certificate validation outcome and accepted all the related risks. Learn more about issues and risks.
