I am having an issue with my load balancer health checks. It is attempting to access the server hosting the Magento 2 site. When I curl the IP address of the machine I get the following Response Headers:

curl -i xxx.xxx.xxx (ip address of the server)

HTTP/1.1 302 Found
Location: https://www.example.com/?SID=79561247abvhemu78nosr0u32l
....

It appears to be redirecting to the domain set inside the Magento2 configuration.

I have read about the SID value. I am not sure if this is causing the redirect but the site will be a multi store site so I would like to keep the SID enabled.

The issue is that when the Load Balancer hits the server I am getting a 302 which causes the health check to fail.

I am unsure of what is causing this redirect and how to best get the health check to pass.

Update

I have confirmed that it is Magento doing the redirect and not the web server. If I remove index.php and replace it with a new php file (Not running Magento) I get a 200 response. So it appears that something in the codebase is creating the redirect.

I ran bin/magento config:show and it returned the following:

web/seo/use_rewrites - 1
web/unsecure/base_url - https://www.example.com/
web/unsecure/base_static_url -
web/unsecure/base_media_url -

Plus a lot more config settings, that seemed irrelevant.
