Can someone please help on what the issue is here.

I have a React web app hosted on Azure Web App. It has been deployed successful.

My problem is, if, for example, I go to the site on myweb.azurewebsites.net it loads well. And if I click on a button like the "signin" button it redirects me to myweb.azurewebsites.net/signin.

However, if I manually type in myweb.azurewebsites.net/signin into the browser, it gives an "Nginx not found" error.

Can someone help on what the issue is. I suspects it's between Azure and/or Nginx.

    Your question is off-topic in StackOverflow. You have a better chance to get it answered if you move it to [Unix & Linux](https://unix.stackexchange.com/tour) or to [Superuser](https://superuser.com). – accdias Mar 31 '22 at 15:00

Nginx not found 404 error means Nginx can’t find the resources your web browser asks for.

  • Check web root directory exists on your server.
  • Make sure your website files are stored in the correct directory.

To resolve "Nginx not found 404 error", please find below workarounds if helpful:

Workaround1:

The most likely issue is that you're not telling Nginx to forward other requests to the /index.html of your application, which makes it so your other pages can't be loaded directly and display a 404 error. To fix this, you'll need to make a small change to your Nginx configuration files.

Make sure your nginx.conf file as shown below:

worker_processes 1;
events {
worker_connections 1024;
}

http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;

#gzip on;
server {
listen 80;
server_name localhost;

location / {
root /home/user_name/Documents/your_proj; # You need to provide here the path of your "index.html" file
index index.html index.htm;
}
}

Workaround2:

If Workaround1 does not work, try changing the location segment as below

location / {

if (!-e $request_filename){

rewrite ^(.*)$ /index.html break;
}
}

Workaround3:

Configure the startup command on "Settings > General settings > Startup Command". Change the path to your build path.

To redirect all queries, use the --spa option:

pm2 serve /home/site/wwwroot/client/build --no-daemon --spa

Workaround4:

In the nginx.conf file, try commenting-out the disable_symlinks on line or changing it to disable_symlinks off.

  • thank you @srideviMachavarapu-MT. I discovered that I didn't add an Nginx conf file and copy it into the Nginx Docker container. Not the correct answer in my specific case but leads me to it. When I did that, it works fine. – Fhuad Balogun Apr 01 '22 at 15:16
