Srping Security + Zuul + Nginx Authentication error handling - spring-boot

Question

I have Zuul and Backend Srping Boot applications and it works just fine without nginx.
So normally it works like that:
User is at http://localhost:8080/auth/login
User types wrong login and password and sends it
User is redirected to http://localhost:8080/auth/login?error and is able to see error message.
Zuul is running on port 8080 and /auth/ is auth application running on another port but I can reach it through Zuul application without knowing exact location of auth application.
But with Nginx user is redirected back to http://localhost:8080/auth/login where ?error is missing and user can't see the error message.
I tried to configure Nginx to use https and to forward requests to my Zuul app that forwads requests to Spring application itself (where Spring Security is).
server {
# Add index.php to the list if you are using PHP
index index.html index.htm index.nginx-debian.html login.html login.htm;
server_name servername.com; # managed by Certbot
location /auth/ {
access_log off;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-Host $host;
proxy_set_header X-Forwarded-Port $server_port;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_pass http://zuul_ip:8080/auth/;
}
gzip on;
gzip_disable "msie6";
gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript application/javascript;
listen [::]:443 ssl; # managed by Certbot
listen 443 ssl; # managed by Certbot
ssl_certificate /etc/letsencrypt/live/servename.com/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/servername.com/privkey.pem; # managed by Certbot
include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}
server {
if ($host = servername.com) {
return 301 https://$host$request_uri;
} # managed by Certbot
listen 80 ;
listen [::]:80 ;
server_name servername.com;
return 404; # managed by Certbot
}
So I need user is redirected back correctly with query param is not deleted from url. How can I achieve this?
