Reverse proxy to Openshift

I was creating reverse proxy to openshift cloud(with TLS: Edge) without any
issue with below configuration:

"server {
    listen 28097;
    server_name localhost;

    location / {
        proxy_pass        ;
        proxy_ssl_verify            off;
        proxy_ssl_session_reuse     on;
        proxy_temp_file_write_size 64k;
        proxy_connect_timeout 10080s;
        proxy_send_timeout 10080;
        proxy_read_timeout 10080;
        proxy_buffer_size 64k;
        proxy_buffers 16 32k;
        proxy_busy_buffers_size 64k;
        proxy_request_buffering off;
        proxy_buffering off;
        proxy_http_version            1.1;
        server_tokens off;

but recently openshift developers created new app with TLS passthrough and
below configuration doesn't work. When I try to do curl I get "HTTP/1.1 503
Service Unavailable".

I don't know what could be the issue. Does anyone have experience with that?
