Hello,

Can somebody enlighten me please?

i have two identical keycloak servers running in HA mode via DNS
discovery keycloak1.my.domain & keycloak2.my.domain

the dns discovery record is: keycloak.my.domain

this part is working no questions.


no i am trying to add nginx to the picture:

upstream signin {
      server 172.19.24.13:8080;
      server 172.19.24.16:8080;
  }

server {

        listen 443;
        ignore_invalid_headers off;
        ssl on;
        ssl_certificate /etc/ssl/my.domain.crt;
        ssl_certificate_key /etc/ssl/my.domain.key;

        server_name signin.my.domain;
        access_log /var/log/nginx/access.log;
        error_log /var/log/nginx/error.log;

        location / {
            proxy_pass          http://signin;
            proxy_redirect      off;
            proxy_set_header    Host               $host;
            proxy_set_header    X-Real-IP          $remote_addr;
            proxy_set_header    X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header    X-Forwarded-Host   $host;
            proxy_set_header    X-Forwarded-Server $host;
            proxy_set_header    X-Forwarded-Port   $server_port;
            proxy_set_header    X-Forwarded-Proto  $scheme;
        }

every request to https://signin.my.domain  results in error 500, and in
logs i see:

rewrite or internal redirection cycle while internally redirecting to
"////////////",

i know exactly that keycloak part work , i could go to
keycloak.my.domain in my browser no problem.
