Cannot upload a larger file nginx - docker

Question

I have configured Nginx with client_max_body_size 100M;
Although still, I am facing an error while uploading a file of 25 MB
The nginx.conf is as follows:
worker_processes 1;
error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;
events {
worker_connections 1024;
}
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
#tcp_nopush on;
keepalive_timeout 65;
#gzip on;
include /etc/nginx/conf.d/*.conf;
}
The ngnix.conf has an included conf file which is as follows:
client_max_body_size 100M;
upstream third-party{
server cognitiveview-thirdparty;
}
server {
listen 443 ssl;
ssl_certificate <key1>;
ssl_certificate_key <key2>;
server_name <>;
server_tokens off;
location / {
proxy_pass http://;
proxy_set_header Host "host.com";
proxy_connect_timeout 1500s;
proxy_send_timeout 1500s;
proxy_read_timeout 1500s;
send_timeout 1500s;
proxy_ssl_server_name on;
client_max_body_size 100M;
}
}
server {
listen 80;
server_name <>;
return 301 https://$host$request_uri;
client_max_body_size 100M;
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
client_max_body_size 100M;
}
location /uploads {
client_max_body_size 100M;
}
}
I tried multiple which suggests setting the client_max_body_size in server, location, and HTTP. As per my understanding, I have updated the values, although still I am not successful in uploading the file for a larger size.
The file is being uploaded through a react application which is going to nginx to a backemd
