I’m currently experiencing an issue with Nginx and my 2nd domain. I have a vps hosted on Hostinger and both of my 2 domains are pointing on it. The problem is that with my 2nd domain, I get a ERR_EMPTY_RESPONSE when trying to access it via web browser or curl: (52) Empty reply from server.

I simplified as much as I can the nginx config to lower down the issue but I always have the same problem.

This is my nginx config :

server {
    listen 80;
    server_name 194.164.XX.XXX www.domain2.com domain2.com domain1.com www.domain1.com;

    location / {
        return 200 'Hello, Nginx is working !';
        add_header Content-Type text/plain;
    }
}

I have access to the Hello message when accessing it via IP address, domain1.com and www.domain1.com but not using the domain2.

I also used dig to verify that the 2nd domain is correctly pointing my vps and it’s the case :

; <<>> DiG 9.18.18-0ubuntu0.22.04.2-Ubuntu <<>> domain1.com

I have no idea where this could come from, any help would be really appreciated.

Thanks in advance.
