Trying to Configure NGINX as Reverse Proxy for RocketChat - nginx

Question

I am trying to configure NGINX as reverse proxy to use the RocketChat Service but the service is not loading on the desired location. The in port is 2357 at which the service(RocketChat) is running and the out port on which it should run is port 3000. Can anyone help me out with this?
Code for the location on which RocketChat should load
I am also adding the docker-compose image infrastructure for reference.
Docker Image Details
nginx.conf file :
location ^~ /chat {
client_max_body_size 200m;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto https;
proxy_set_header X-Nginx-Proxy true;
proxy_redirect off;
proxy_pass http://rocketchat:3000/;
}
docker-compose-org.yml:
# Image--infrastructure:rocketchat
rocketchat:
image: rocketchat/rocket.chat:latest

bash -c
"for i in `seq 1 30`; do

Answer 1

NGINX is receiving http/https requests and the proxy configuration should pass those requests to the host and port on which rocketchat is listening.
In your docker-compose.yaml file, you specify the rocketchat service and map port 2357 on the host machine to port 3000 in the container.
So which that said, if NGINX is running on the host machine as a linux service (not as part of the docker-compose file) then you need to edit the last line of the NGINX configuration for the location to point to localhost:2357:
proxy_pass http://localhost:2357
