Increasing File Upload size with a nginx nodejs droplet

I am unsure where to find the error (attached the screenshots below).

So Upon trying to upload large files through a Droplet, Ubuntu, Nginx, Nodejs I am hitting a 413 Request Entity Too Large error.

Connection: keep-alive

Content-Length: 67

Content-Type: text/html

Date: Mon, 29 May 2023 21:27:18 GMT

Server: nginx/1.22.0 (Ubuntu)

X-Powered-By: Express

In the response headers I get :

Server:
nginx/1.22.0 (Ubuntu)

X-Powered-By:
Express

which tells me (I think) it’s coming from Nginx config (image/link below). In the /etc/nginx/nginx.conf I have within the http block client_max_body_size 200M however i’m still getting this 413 error.

So I’m unsure, is the error coming from Nginx and the client_max_body_size is not being picked up/listened too OR is there a limit on a single upload request and DigitalOcean is hitting some limit, I’m unsure how to have a definite answer, since I can assume it’s nginx but with the config looking correct I am unsure if it’s still nginx or DO.

Thanks
