CORS preflight Major Issue

[coommark]

Issue Type: I have a proxy exactly like the sample here, hosted on https://search.commercesite.com. The client is hosted on https://www.commercesite.com. On elasticsearch.yml, I have the usual

http.cors.enabled: true
http.cors.allow-credentials: true
http.cors.allow-origin: /https?:\/\/(localhost)?(127.0.0.1)?(:[0-9]+)?/
http.cors.allow-headers: X-Requested-With, X-Auth-Token, Content-Type, Content-Length, Authorization, Access-Control-Allow-Headers, Accept

Below is the reactivesearch setting used to connect to the proxy:

export const settings = {
    url: 'https://search.commercesite.com/',
    app: 'commercesite',
    type: 'products'
};

Everything worked fine during testing, until I added SSL to both services on launch date, then the CORS issues started, the error being like this:

Failed to load https://search.commercesite.com/commercesite/products/_msearch?: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://www.commercesite.com' is therefore not allowed access

Platform: Web, SSR

I added this express cors package to https://www.commercesite.com, however the error persisted. My thinking is reactivesearch calls the proxy directly, as a result the cors package will not be of value here.

Long story short, we suspended our big launch day because of cors! How ironic right?

Ok now PLEASE HELP!

@coommark Did you add something like Nginx for configuring SSL? The same things that you did to Elasticsearch in terms of allowing CORS will have to be applied there too.
