After applying SSL the Login is not showing

We are using Nexus Repository Manager version OSS 3.15.2-01,
We using Let’sencrypt for SSL, And we are using Nginx for the proxy server.
After applying SSL for Nexus repository, we could not able to see the login screen,
The login screen is seen in the IP but in URL it’s not showing the login screen,
Here I have attached the screenshot of the error which we facing.
Can anybody help me with this?

Is nginx configured using our recommended settings?

i believe i have my configuration close to what is needed but i keep getting connection refused…when attempting docker login can you provide any suggestions for setting up the configuration … here is a sample

    index index.html index.htm index.nginx-debian.htm index.jsp;
    server_name ; # managed by Certbot

    location / {
            # First attempt to serve request as file, then
            # as directory, then fall back to displaying a 404.
            try_files $uri $uri/ =404;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $remote_addr;
            proxy_set_header Host $host;

            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Forwarded-Proto "https";
