Error in Production for Login Auth

Do you see any error logs on the server or in the console? A common issue is forgetting to add your domain to the allowed origins list.

I am using NGINX with the configuration like below :

    server_name mydomain.com www.mydomain.com;
    if ($host = www.mydomain.com) {
    return 301 $scheme://mydomain.com$request_uri;
    }

    location / {
            allow all;
            # Proxy Headers
            proxy_http_version 1.1;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header Host $http_host;
            proxy_set_header X-Cluster-Client-Ip $remote_addr;
            # WebSockets
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "upgrade";

            proxy_pass http://phoenix;
    }

Does I miss some configuration in my phoenix app ?

What do you have configured in your check_origin value in your Phoenix config? Also, did you see my question regarding error logs?

Dear Sir,
I don’t know to see the error logs in production mode

And I don’t know the exact line code to configure that,

it’s solved thankyou Sir
I forgot to change the example.com to my domain name in folder config the file runtime.exs

host = System.get_env("PHX_HOST") || "example.com"

become

host = System.get_env("PHX_HOST") || "mydomain.com"
