Hi Carolina,

I am really sorry for the delay of this reply. I've helped you with the facebook login setup on your site. However it seems like when I'm trying to login into your site via facebook, the following error message will appear,

Failed to connect to 2a03:2880:1010:6f03:face:b00c:0:2: Network is unreachable

It appears that the issue lies with the web hosting server firewall. Their firewall may have been configured in a way that your website unable to reach the Facebook server. Can you consult with your web hosting service provider regarding on this error and kindly get back to us once they have reply to your inquiry.
