Invalid response while renewing domains Letsencrypt Certificate

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

Issue Details: I am running compiled version of Nginx 1.22.0 on RHEL8.8. It is working fine. But facing issues with some domain renewal. One of them is staging.ezchat.ai.

My domain is: staging.ezchat.ai

I ran this command: certbot renew --cert-name staging.ezchat.ai -v

It produced this output:

Saving debug log to /var/log/letsencrypt/letsencrypt.log

Processing /etc/letsencrypt/renewal/staging.ezchat.ai.conf

Certificate is due for renewal, auto-renewing...

http-01 challenge for staging.ezchat.ai

Certbot failed to authenticate some domains (authenticator: nginx). The Certificate Authority reported these problems:
Domain: staging.ezchat.ai
Type: unauthorized
Detail: 117.20.23.229: Invalid response from https://staging.ezchat.ai/.well-known/acme-challenge/AXkBSxrgLo_HkCneMqLMevCBZfU_k1dxqvPrpXei0P4: 404

Hint: The Certificate Authority failed to verify the temporary nginx configuration changes made by Certbot. Ensure the listed domains point to this nginx server and that it is accessible from the internet.

My domain config is as below:

server {
   server_name  staging.ezchat.ai;

   access_log    /var/log/nginx/staging.ezchat.ai.access.log  main;
   include include/error.conf;

location /.well-known/acme-challenge {
    alias /var/www/html/.well-known/acme-challenge;
    try_files $uri =404;
}

 location / {
        proxy_pass    http://192.168.0.244:9000/;
        include include/proxy.conf;
    }

    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/staging.ezchat.ai/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/staging.ezchat.ai/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

}
server {
    if ($host = staging.ezchat.ai) {
        return 301 https://$host$request_uri;
    } # managed by Certbot

   listen 80;
   server_name  staging.ezchat.ai;
    return 404; # managed by Certbot
}

Even i added below config in domain config file in it. but still getting same error. My other successfully renewed domain did not have this configuration.

location /.well-known/acme-challenge {
    alias /var/www/html/.well-known/acme-challenge;
    try_files $uri =404;
}
