Problem with 403 in response to curl on server and locally but it works after adding no-cache...

I have a problem with my server and locally from my computer. When I try to make a curl query to my server (using Nginx), I get a 403 Forbidden response. However, if I add the Cache-Control header: no-cache, no-store, must-revalidate and Pragma: no-cache, the query works fine and gets a 200 response.

This is config Nginx for my api.


server {
server_name api.mydomain.pl;
listen 443 ssl;


ssl_certificate /etc/letsencrypt/live/api.mydomain.pl/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/api.mydomain.pl/privkey.pem;
include /etc/letsencrypt/options-ssl-nginx.conf;
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem;


location /api/ {


if ($request_method = 'OPTIONS') {
add_header 'Access-Control-Allow-Origin' 'https://mydomain.pl' always;

return 204;
