Permission denied error when trying to access magento2 prior to installation on Ubuntu 20.04 / nginx / php 7.4

Question

What I've done so far,

Installed nginx 1.19.6 Installed php 7.4 and all required extensions in Magento Documentation Installed and configured MySQL as per documentation, and created magentodb Installed Elasticsearch 7.x (Success) Installed Redis-server (Success) DID NOT install Varnish since the Magento documentation states that it does not support SSL and I can't run my magento store without SSL.

Downloaded Magento 2.4.1 Community edition with sample data Moved to the chosen root directory @ /var/www/

Created Non-root sudo user, and carefully provided all the necessary permissions.

Usually, I get a magento welcome page like this one:

But this time, i rebuilt my whole droplet making sure i didn't miss any of the details that caused me errors before. This time I'm getting an "Unable to connect" error in my browser, and sending a GET request from terminal is returning the below error.

curl -XGET 'https://mydomain/'

curl: (7) Failed to connect to mydomain port 443: Connection refused

ping to mydomain successfully points to my cloud IP address

PING mydomain (ipv4-xxx-xx-xxx) 56(84) bytes of data.
64 bytes from ipv4-xxx-xx-xxx (ipv4.xxx.xx.xx): icmp_seq=1 ttl=53 time=167 ms

GET Request to my localhost on my server successfully returns the Nginx welcome page:

 curl -XGET 'localhost'
<!DOCTYPE html>
<html>
<head>
<title>Welcome to nginx!</title>
<style>
    body {
        width: 35em;
        margin: 0 auto;
        font-family: Tahoma, Verdana, Arial, sans-serif;
    }
</style>
</head>
<body>

Does anyone have a hint where to go from here?

Update: I am running Magento 2.4.1 Community Edition

Nginx Status

Active: active (running) since Fri 2021-01-22 19:26:03 UTC; 15h ago

Nginx -t

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok nginx: configuration file /etc/nginx/nginx.conf test is successful

PHP7.4-FPM status

Active: active (running) since Fri 2021-01-22 18:49:59 UTC; 16h ago

Didn't install varnish since the Magento Docs state that it doesn't support SSL.

Yes my configuration file is symlinked to /sites-enabled/

This is my /sites-available/* config file

upstream fastcgi_backend {
        server  unix:/run/php/php7.4-fpm.sock;
}

server {
    listen 80;
    listen [::]:80;
    server_name mydomain;
    return 301 https://$server_name$request_uri;
}

server {

        listen 443 ssl;
        server_name mydomain;

        ssl_certificate /etc/letsencrypt/live/mydomain/fullchain.pem;
        ssl_certificate_key /etc/letsencrypt/live/mydomain/privkey.pem;

        set $MAGE_ROOT /var/www/magento2;
        set $MAGE_MODE default;
        include /var/www/magento2/nginx.conf.sample;
}

Also, I have UFW enabled with the following allowed connections

Status: active

     To                         Action      From

Debug advices first:

can u run sudo systemctl status nginx
can u run sudo systemctl status php7.x-fpm # hint: replace x with your php version
Is varnish enabled and which version of varnish do you use?
sudo varnishd -V
sudo systemctl status varnish
which magento2 version are u running?

Please provide your configurations located in: /etc/nginx/sites-available/<<your conf file>>

Is your conf file available in /etc/nginx/sites-enabled/<<your conf file>>

I installed Magento 2.4.x and 2.3.x a lot of times and can give u a lot of really detailed instructions that you can follow. Just ask me ;)

UPDATE 24.01.2020 23:00:00:

Hello,

First of all: Your questions is really really general and can have different problems at different locations. Of course it is possible to use varnish cache with ssl. You can add varnish as a reverse proxy between nginx server ports. It is really recommend to use varnish because otherwise Magento2 is so slow. You will use important conversion rate and loose also customers because everything will take so long...

One example is this website that I am working on. It uses nginx webserver, varnish cache 6 (varnish cache 5 caused a lot of problems ob Ubuntu 18.04) and also an automatic cache warmer (auto crawler for my website)
https://www.goldschmiede-jaqueline.de/

I followed these instructions:
https://olegnax.com/speed-up-magento-2-with-varnish-and-nginx-as-ssl-termination-on-ubuntu/

TO YOUR ISSUE:

I think that you have maybe some path failures and maybe also permission problems.

Replace all 7.3 with 7.4 when using magento 2.4.x
Replace goldschmiede-jaqueline with yourdomain

If u run one store without any different domains/subdomains then your folder should approximately like the following picture:

Inside etc/nginx/sites-available/goldschmiede-jaqueline.de

upstream fastcgi_backend {
     server  unix:/run/php/php7.3-fpm.sock;

Your path to magento2 root should look like that:
/var/www/goldschmiede-jaqueline.de

Get sure that your user have enough permissions.
sudo chmod 755 /var/www
Please enable port 80 as well - use this script in your shell-

sudo ufw default deny incoming && \
sudo ufw default allow outgoing && \
sudo ufw allow ssh && \
sudo ufw allow http && \
sudo ufw allow https && \
echo "y" | sudo ufw enable

If u have problems contact me directly over demir.[email protected] and we can do a teams call or sth. similiar :P

Hi I updated the answer. U can contact me directly per Mail when you have questions. [email protected] — Samuel Demir, Jan 24, 2021 at 22:33
