How to reversely proxy AllTalk with Nginx?

[MoRanYue]

🔴 If you have installed AllTalk in a custom Python environment, I will only be able to provide limited assistance/support. AllTalk draws on a variety of scripts and libraries that are not written or managed by myself, and they may fail, error or give strange results in custom built python environments.

🔴 Please generate a diagnostics report and upload the "diagnostics.log" as this helps me understand your configuration.

Describe the bug
Many main functions did not work. Using browser on my server to access localhost:7852, everything worked well.

To Reproduce
Nginx <-> AllTalk Gradio Interface (127.0.0.1:7852), with the latter's proxy system disabled.

Screenshots
Nginx configuration:

server {
        listen 8000 ssl;
        server_name example.com;
        http2 on;

        ssl_certificate chain.pem;
        ssl_certificate_key key.pem;

        client_max_body_size 0;

        location / {
            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;
            proxy_set_header Host $http_host;

            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "upgrade";

            proxy_http_version 1.1;
            proxy_buffering off;
            proxy_cache off;

            proxy_read_timeout 3600;
            proxy_send_timeout 3600;

            proxy_pass http://127.0.0.1:7852;
        }
    }
