Scroll search not working after using NGINX proxy

Elastic Stack Elasticsearch
1

Hello, I am trying to route my elasticsearch.js queries through nginx (so that i can set the elasticsearch network.host to 127.0.0.1).

I added this to my nginx config so that anything that hits my domain name with _search get routed to 127.0.0.1:9200:

location ~ ^/.*/_search$ {
proxy_pass http://127.0.0.1:9200;
}

My search queries have scroll enabled since some of them can return quite a lot of records. If the search only brings back a few rows then it works fine but if it has to scroll it errors.

When it scrolls i get this error:

Request URL:https://mysite.mydomain.com/_search/scroll?scroll=30s
Request Method:POST
Status Code:400 Bad Request
Remote Address:serverIP:443

EDIT

When i scroll without it going through NGINX it looks like this:
Request URL:http://serverIP:9200/_search/scroll?scroll=30s
Request Method:POST
Status Code:200 OK
Remote Address:serverIP:9200

The only difference i see (appart from the domain vs server ip) is that the remote address on the none nginx is 9200 where as with NGINX is 443)

I guess i am missing a setting in NGINX to make this work

EDIT

Anyone have any ideas why scroll will not work?

Another edit... It doesnt matter if i use 443 or not - if i isolate the _search on any port it does the same..

It gives the following error:

No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:9000'

Elasticsearch config has the following:

http.cors.enabled: true
http.cors.allow-origin: "*"

if i add the header via nginx it gives this error:

The 'Access-Control-Allow-Origin' header contains multiple values '*, *', but only one is allowed

Why does it single out the scroll request but nothing else?

Thanks

Never mind.. the issue was with my regex only matching URLs that ended with _search rather than contains _search.: location ~ _search {}
