502 Bad Gateway on Nginx with Laravel, PHP 8.3, and Ubuntu 24.04

I’ve set up Nginx 1.24.0 on Ubuntu 24.04 LTS, installed PHP 8.3 (PHP 8.3.6), and deployed a fresh Laravel 11.2 project. I created a virtual host on port 82 for telegrambot.test. However, when I try to access http://telegrambot.test:82, I get a 502 Bad Gateway error.

Here’s my Nginx config (nginx.conf):

I installed a fresh Laravel application under /var/www/telegrambot and set the public folder as the document root. I expected to be able to access the Laravel app by visiting http://telegrambot.test:82, but instead, I got a 502 Bad Gateway error.

After reviewing my configuration, I noticed that the fastcgi_pass directive in my Nginx configuration is pointing to the PHP 7.4 FPM socket, while I am using PHP 8.3. I think this might be the root cause of the issue.

I ran the following command to check for the correct PHP 8.3 FPM socket:

sudo find /var/run/php/ -name "php8.3-fpm.sock"

Based on the result, I updated my Nginx configuration to:

fastcgi_pass unix:/var/run/php/php8.3-fpm.sock;

However, the problem persists, and I am still getting the 502 Bad Gateway error. I also confirmed that both the Nginx and PHP-FPM services are running correctly.

I’ve tried a simple php script (phpinfo()) and it works perfect

I’m expecting Laravel to load properly when I access http://telegrambot.test:82, but instead, I keep getting this gateway error. Any suggestions on what else I should check or configure?
