This is a common question we get from customers.
When I curl to the site, it gives me an error of
$ curl https://www.example.com curl: (51) SSL: certificate subject name 'www.squixa.com' does not match target host name 'www.example.com'
This is because section.io uses SNI to negotiate SSL(see https://en.wikipedia.org/wiki/Server_Name_Indication). You will need to add the host header to the curl command
$ curl -H "Host: www.goabroad.com" https://www.goabroad.com
