Request in api with nginx as proxy get 504 Gateway Timeout - nginx

Question

In a specific route i getting this error 504 Gateway timeout.
That route takes more time, about 7 seconds.
I need in a specific route give more time. Its a POST route.
I have search and configure my nginx (locate: nginx/sites/available) file like this:
server {
server_name servername.com.br;
location /api/branch-company {
proxy_read_timeout 30s;
proxy_connect_timeout 30s;
proxy_send_timeout 30s;
if ($request_method = POST) {
proxy_pass http://localhost:5001;
}
proxy_pass http://localhost:5001;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection keep-alive;
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
location /pdf-generator {
rewrite ^/pdf-generator(/|$)(.*) /$2/ break;
proxy_pass http://localhost:3001;
}
location / {
proxy_pass http://localhost:5001;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection keep-alive;
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
listen 443 ssl; # managed by Certbot
ssl_certificate /etc/letsencrypt/live/servername.com.br/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/servername.com.br/privkey.pem; # managed by Certbot
include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}
server {
if ($host = servername.com.br) {
return 301 https://$host$request_uri;
} # managed by Certbot
listen 80;
server_name servername.com.br;
return 404; # managed by Certbot
