How can I access the public IP address of the client behind a DO load balancer?
Does the load balancer send any header with this IMPORTANT info? Can’t find it in my $_SERVER info array :(
thanks!

If you use var_dump( $_SERVER ); are you not seeing X-Forwarded-For?
You’ll want to look for HTTP_X_ headers when it comes to fetching information coming from the LB, such as the proto (HTTP/HTTPS), port, and client IP.
HTTP_X_FORWARDED_PORT
HTTP_X_FORWARDED_PROTO
HTTP_X_FORWARDED_FOR
It was an NGINX config issue.

That’s what I initially though about, but there is nothing in phpinfo() in the $server section. Nothing like HTTP_X_FORWARDED
weird
