I am using nginx as a reverse proxy to serve my various node and react applications. Basically I set a subdomain for each application.

I can query https://demo.myapp.com/ and it gets passed to the correct underlying app but if I query https://demo.myapp.com/login I get a 404. note that I get "404 Not Found" as plain text, no html no nothing.

I find this odd because I copy pasted the config of my other apps and I can definitely call https://myotherapp.myapp.com/login. I have looked online but I didn't find any help on this matter (because I didn't really find a way to formulate my problem ?)

Here's my config (domain names are anonymized but it's exactly the same structure)

 server 
 listen 80 default_server;
 listen [::]:80 default_server;
 server_name _;
 return 301 https://$host$request_uri;


# this one works fine when I call sc.example.io/login
server 
 server_name sc.example.io;

 location / 
 proxy_pass http://127.0.0.1:5102;
 

 listen 443 ssl; # managed by Certbot 
 ssl_certificate /etc/letsencrypt/live/example.io/fullchain.pem; # managed by Certbot 
 ssl_certificate_key /etc/letsencrypt/live/example.io/privkey.pem; # managed by Certbot 
 include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot 
 ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot 


#this ones 404's when I call demo.example.io/login
server 
 server_name demo.example.io;

 location / 
 proxy_pass http://127.0.0.1:5110;
 


 listen 443 ssl; # managed by Certbot 
 ssl_certificate /etc/letsencrypt/live/example.io/fullchain.pem; # managed by Certbot

 ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot 



server 
 if ($host = sc.example.io) 
 return 301 https://$host$request_uri;
 # managed by Certbot 


 server_name sc.example.io;
 listen 80;
 return 404; # managed by Certbot
