Proxy to App on another server using Sub-Folder

I'm currently struggling to correctly proxy to an app on another server using nginx.
However I have an issue where as the proxy does not fully work and I get a 404 error from the other server,

This is my current nginx config for this specific case:

include includes/lb-realIPs.conf;

map $http_upgrade $connection_upgrade {

default upgrade;

'' close;

map $host $upstream_uicontroller {



server {

listen ssl proxy_protocol;

include includes/certs/cert-wildcard-nethavn.net.conf;
include includes/certs/ssl-base.conf;

server_name ui-controller.nethavn.net;

location ~/(ui)/ {
proxy_pass https://$upstream_uicontroller:8443;
proxy_http_version 1.1;

proxy_buffering off;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";

proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;

deny all;

include includes/inc-nethavn.conf;
location ~ /\.ht {
deny all;

I tried many solutions on stackoverflow and Google but none are working.

Basic goal at the end is that I can call https://ui-controller.nethavn.net/ui/ and the app on the other server just adds their stuff after the /ui/ and works as if it would be in the root (/) path.

Can you please assit me here? Thanks!

Kind Regards,
