    Hi @hasintha86

    cURL problems are usually related to a server configuration. You can receive the error code 28, ( which actually indicate operation timeout errors ) by either:

    • an outdated PHP or cURL version
    • memory limit problem
    • SSL issue ( since you told you changed the domain name, my guess is this )
    • a server configuration or firewall setting for example a ModSecurity which prevents certain requests, which is necessary for the OAuth2 authorization what we use in Nextend Social Login. ( Basically your server send requests to the server of the provider ( e.g. Google) and then it should receive a response from it. If the communication is prevented by a server setting, then the verification can not work either. )

    So I would suggest getting in touch with your server host, telling them about this error code. They will most likely be able to help in identifying and fixing the problem.

    Note: you can find a good article, about cURL error: 28. If your host can not find a problem with the settings mentioned above, they could also check the steps of this article:

    Best regards,
    Laszlo.
