Nginx代理从https到ws

Question

我正在运行Nginx服务器。我已经安装了certbot的证书。 所以现在它对于Http和Https都可用。 现在的问题是我无法访问其中的websocket。 它给出了ws不安全的错误，您正在尝试使用https访问它。尝试使用WSS而不是WS。我无法使用WS。 我可以做某种代理使WS与https一起工作吗？

完整错误为： “ https://chain.com/”上的页面已通过HTTPS加载，但尝试连接到不安全的WebSocket端点“ ws：//123.3.6.5：7546 /”。该请求已被阻止；该端点必须可以通过WSS使用。

我的nginx配置是..

 server{
    server_name         chain.com www.chain.com;
    root                /home/ubuntu/chain.com/app;


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

 location / {
