Microsoft Azure | Connect to website without port using 443

Question

VM Info:

• Ubuntu 18
• 2vcpus and 8gb ram
• Running Express/HTTP (is that a problem?) server on Node

Currently, connecting to my website (ip: http://20.62.174.185) works but you have to include the port at the end of the website, even when using 443 and connecting using HTTPS.

I'm connecting to https://20.62.174.185 and it doesn't work but https://20.62.174.185:443 works. My NSG has HTTPS priority at 301, right above SSH at 300.

Edit: http://..*.185:443 works, not https
so it's a problem with not going to https at all

Answer 1

Looks like, you can correct it in Nginx config. open default file under the folder /etc/nginx/sites-enabled/ and add the contents similar to the following:
I am not able to paste the code here. So, attaching it as a notepad

250679-nginx.txt

Copy the file to /etc/nginx/sites-available/ and restart Nginx to see if it helps

Answer 2

When the browser navigates to https://20.62.174.185, it uses SSL/TLS protocol to establish a connection to port 443.

As in your case, you said that http://..*.185:443 works, we know that you mistakenly configured port 443 to work with HTTP, not HTTPS.

You can find how to configure HTTPS sites from NGINX official sample, https://nginx.org/en/docs/http/configuring_https_servers.html

   server {  
       listen              443 ssl;  
       server_name         www.example.com;  
       ssl_certificate     www.example.com.crt;  
       ssl_certificate_key www.example.com.key;  
       ssl_protocols       TLSv1 TLSv1.1 TLSv1.2;  
       ssl_ciphers         HIGH:!aNULL:!MD5;  
       ...  
   }
