I have replaced IP address’ first dot below with an underscore because when I attempt to create this topic, the forum pushes back and says that I can only include 2 links in a post. Sorry.
**My issue:
Hello. I am looking for help with an NGINX/Raspberry Pi 4 Hotspot/Node-RED reverse proxy implementation. Furthermore, I am utilizing NetworkManager and dnsmasq. As far as I can tell, I have everything set up per the instructions I have found on various bulletin boards, FAQ’s etc., etc. Apparently not…
I have a Raspberry Pi 4 set up as a Hotspot (which apparently isn’t the same as an access point). The hotspot performance of our application is better than that of an access point, so we need to leave it as-is.
I have two Node-RED instances running. The Raspberry Pi’s wired port is not connected. When I connect to the hotspot on my computer or phone, I can see that the DNS address points to the Raspberry Pi. I think this is simply because I have stated in the NetworkManager setup that is the DNS address.
I have set up my /etc/nginx/conf.d/remote.conf file as:
server
{
listen 80;
server_name field.interface;
location /
{
resolver 127_0.0.1;
proxy_pass http://10_0.123.1:1880/ui/;
}
}
server
{
listen 80;
server_name stmu.viewer;
location /
{
resolver 127_0.0.1;
proxy_pass http://10_0.123.1:1881/ui/;
}
}
When I try going to “field.interface/” or “stmu.viewer/”, I get a web browser error that the page is not found. I have to include the trailing ‘/’ or else the web browser tries to perform a Google search. If I redirect to the actual address (10_0.123.1:1880:ui or 10_0.123.1:1881:ui), the pages show up just fine. If I do a “curl field.interface” within a SSH session, the system responds to the name.
Here’s the strange point. If I connect to our corporate LAN, then I can connect via server name on either my computer or my phone. Once I disconnect from the corporate LAN, I can still connect via name. Once I reboot the Raspberry Pi, it goes back to no name resolution. This is web browser independent.
I am sure I am leaving out some configuration file information you will need to answer this question; apologies in advance. Suggestions are greatly appreciated. Thank you.

How I encountered the problem: installed NGINX per websites’ suggestions
Solutions I’ve tried:
Version of NGINX or NGINX adjacent software (e.g. NGINX Gateway Fabric): 1.22.1
Deployment environment: Raspberry Pi debian
Minimal NGINX config to reproduce your issue (preferably running on https://tech-playground.com/playgrounds/nginx for ease of debugging, and if not as a code block): (Tip → Run nginx -T to print your entire NGINX config to your terminal.)
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok

NGINX access/error log: *(Tip → You can usually find the logs in the /var/log/nginx directory.)
Not sure which file you would like to se here. There is nothing in error.log and access log (since reboot) is
127.0.0.1 - - [28/Oct/2025:07:22:12 -0500] “GET / HTTP/1.1” 200 1733 “-” “curl/7.88.1”
