NGINX error SSL Sur Tomcat

Bonjour,

J'ai mis en place un vhost sur NGINX avec SSL cerbot,
Hors HTTPS cela fonctionne mais des que j'active le HTTPS, je n'arrive pas à faire fonctionner le proxypass /porte (tomcat)

Si quelqu'un à une idée de cette raison

server {
listen [::]:443 ssl ipv6only=on; # managed by Certbot
listen 443 ssl; # managed by Certbot
ssl_certificate /etc/letsencrypt/live/mydomain.com/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/mydomain.com/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

root /var/www/html/mydomain;

index index.html;
server_name mydomain.com www.mydomain.com;

location / {
    try_files $uri $uri/ =404;
}

location /porte {
    proxy_pass http://127.0.0.1:4070;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_set_header Host $host;
}

}

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

listen 80;
listen [::]:80;
server_name mydomain.com www.mydomain.com;
return 404; # managed by Certbot

}

J'ajoute que j'obtiens l'erreur ERR_SSL_PROTOCOL_ERROR
