Nginx: Reverse proxy setup gives a 404 error - linux

Question

I have set a simple reverse proxy setup on my nginx server
user www-data;
worker_processes auto;
pid /run/nginx.pid;
include /etc/nginx/modules-enabled/*.conf;
events {
worker_connections 768;
# multi_accept on;
}
http {
##
# Basic Settings
##
sendfile on;
tcp_nopush on;
types_hash_max_size 2048;
# server_tokens off;
# server_names_hash_bucket_size 64;
# server_name_in_redirect off;
include /etc/nginx/mime.types;
default_type application/octet-stream;
##
# SSL Settings
##
ssl_protocols TLSv1 TLSv1.1 TLSv1.2 TLSv1.3; # Dropping SSLv3, ref: POODLE
ssl_prefer_server_ciphers on;
##
# Logging Settings
##
access_log /var/log/nginx/access.log;
error_log /var/log/nginx/error.log;

# Gzip Settings

# gzip_comp_level 6;
# gzip_buffers 16 8k;
# gzip_http_version 1.1;

##
# Virtual Host Configs
##
# include /etc/nginx/conf.d/*.conf;
include /etc/nginx/sites-enabled/*;
}
and only file in /etc/nginx/sites-enabled
server {
listen 80 default_server;
listen [::]:80 default_server;
index index.html index.htm index.nginx-debian.html;
location /portainer/ {
proxy_pass http://127.0.0.1:9445;
}
}
on trying to access the server http://192.168.29.118/portainer/ I get 404 page not found response, although I'm able to access http://192.168.29.118:9445 and curl http://127.0.0.1:9445
my access.log looks like this and nothing on my error.log
192.168.29.67 - - [21/Oct/2022:13:20:43 +0000] "GET /portainer/ HTTP/1.1" 404 43 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:106.0) Gecko/20100101 Firefox/106.0"
Have tried looking answers for similar questions but haven't found anything solid to make my config work, appreciate any help!
