I have installed nginx version: nginx/1.15.11 in server. And config file looks as below

server {
    listen 80 default_server;
    listen [::]:80 default_server;
    server_name hub.sigmabh.io;
    return 301 https://***.***.io$request_uri;
}

server {
   listen 443 ssl;
   ssl_certificate /etc/ssl/***.pem;
   ssl_certificate_key /etc/ssl/***.pem;
   ssl_prefer_server_ciphers on;
   ssl_protocols TLSv1.3;
   ssl_ciphers TLS13-CHACHA20-POLY1305-SHA256:TLS13-AES-256-GCM-SHA384:TLS13-AES-128-GCM-SHA256:EECDH+CHACHA20:EECDH+AESGCM:EECDH+AES;
   server_name ***.***.io;
   server_tokens off;
   client_max_body_size 3M;

location /static/ {
   alias /home/***/static/;
}
location /static/admin {
   alias /home/***/admin/;
}


location / {
    proxy_pass https://*.*.*.*:4000/;
    proxy_set_header Host $host;
    proxy_ssl_server_name on;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
}
}

I have enabled tls1.3 in google chrome and if I make a request from the browser, the application is not loading. I am getting ""There was a problem with the handshake. The site may not support a protocol or cipher we can use."", if I scan the URL.

TLS1.2 is working fine. Openssl version is OpenSSL 1.0.2o 27 Mar 2018.
