HTTP Error 405 Method Not Allowed from AZURE - node.js

Question

Looking for some assistance with this error.
After hosting my Node.js & Angular project at azure I'm getting that error on POST request:
Http failure response for https://https://green-market.azurewebsites.net/api/auth/login: 405 Method Not Allowed
This is my web.config file:
<?xml version="1.0"?>
<configuration>
<system.webServer>
<httpProtocol>
<customHeaders>
<add name="Access-Control-Allow-Origin" value="*" />
<add name="Access-Control-Allow-Methods" value="GET, PUT, POST, DELETE, HEAD" />
<add name="Access-Control-Allow-Headers" value="Origin, X-Requested-With, Content-Type, Accept" />
</customHeaders>
</httpProtocol>

<add name="iisnode" path="app.js" verb="*" modules="iisnode"/>

<add input="{REQUEST_FILENAME}" matchType="IsDirectory"

</conditions>
<action type="Rewrite" url="/" />
</rule>
</rules>

<mimeMap fileExtension="woff" mimeType="application/font-woff" />
<mimeMap fileExtension="json" mimeType="application/json" />
</staticContent>
</system.webServer>
</configuration>
And this is my app.js file from node.js server:
let originUrl;
if (process.env.PORT) {
global.config = require("./config-prod");
originUrl = "https://green-market.azurewebsites.net";
}
else {
global.config = require("./config-dev");
originUrl = "http://localhost:4200";
}
require("./data-access-layer/dal");
const express = require("express");
const session = require("express-session");
const path = require("path");
const cors = require("cors");
const productsController = require("./controllers/products-controller");
const authController = require("./controllers/auth-controller");
const shoppingCartsController = require("./controllers/shopping-carts-controller");
const ordersController = require("./controllers/orders-controller");
const citiesController = require("./controllers/cities-controller");
const server = express();
const fileUpload = require("express-fileupload");
const { request, response } = require("express");
const { url } = require("inspector");
server.use(fileUpload());
server.use(express.json());
server.use(express.static(path.join(__dirname, "./_front-end")));
server.use(cors({
origin: originUrl,
credentials: true
}));
server.use(session({
name: "OnlineMarketSession",
secret: "itsASecret",
resave: true,
saveUninitialized: false,
}));
server.use("/api/products", productsController);
server.use("/api/shopping-carts", shoppingCartsController);
server.use("/api/orders", ordersController);
server.use("/api/auth", authController);
server.use("/api/cities", citiesController);
// Any other route - return index.html as we are SPA:
server.use("*", (request, response) => {
response.sendFile(path.join(__dirname, "./_front-end/index.html"));
});
const port = process.env.PORT || 3000;
server.listen(port, () => console.log(`Listening on port ${port}`));
Thank you!
