Hi,

Please kindly post more information on the server's SSL certification. (Please kindly HIDE any sensitive information like URL, Common Name...etc)

Check that if you have trusted the whole certificate chain (Root CA, intermediate CA); check if the certification is not expired; also check if the encryption method (SSL 3.0 / TLS 1.0 / TLS 1.1...etc) that your browser could support.

Hi @ngkin2010 ,

Thank you so much for your reply. I have added that certificate to Trusted Root Certification Authorities folder (I refereed this link https://docs.microsoft.com/en-us/skype-sdk/sdn/articles/installing-the-trusted-root-certificate). But I'm getting the same error. Please see below for certificate details.

In this below pic, Root CA is not trusted and Intermediate CA is trusted, but I've added it to Trusted Root Certification Authorities folder of both Local Computer & Current User.
