Impossible to open URL even with no web filter

[jchavezb]

I installed the opnsense with Transparent Web Proxy and Web Filter Shalla.

I dont know why I cant open the URL https://www.bancofalabella.cl/.  I am receiving the follow error when I inspect the webpage.

Access to XMLHttpRequest at 'https://cntn.bancofalabella.cl/spaces/p6eyia4djstu/environments/master/entries?content_type=configuraciones&fields.channel=public-web' from origin 'https://www.bancofalabella.cl' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

From my cellphone this web page open normally with no using the opnsense.

It is a Proxy Web Bug?
