    given you are on windows please try the following and let us know of it worked

    Change your DNS server to 8.8.8.8 on the network card of the PBX
    Open a CMD and and perform an ipconfig /flushdns
    Restart the services including the Nginx service from services.msc
    Try launching the config wizard again
