title: nginx proxy server not able to upload files greater then 1 MB
body: <p>Below is my nginx conf I am using (nginx is a docker container)- Nginx is used as a proxy server to all backend api servers. When I am tried to upload file I am getting error if size is greater then 1 MB. Tried all possible solution given but cloudn't resolve. Any help would be useful.</p>
