    I am using Postman with OAuth, with gmail account. I can send email from anywhere except the host server network (LAN).

    Email Log says that the error is:
    Error executing wp_remote_post: Peer certificate cannot be authenticated with known CA certificates.

    Any help would be highly appreciated.
