Hi @FluffyDiscord, did you run Nginx UI behind a reverse proxy?

[0xJacky]

If so, please modify the configuration file to allow Nginx to handle WebSocket requests for Nginx UI.

server {
    listen          80;
    listen          [::]:80;

    server_name     <your_server_name>;
    rewrite ^(.*)$  https://$host$1 permanent;
}

map $http_upgrade $connection_upgrade {
    default upgrade;
    ''      close;
}

server {
    listen  443       ssl;
    listen  [::]:443  ssl;
    http2   on;

    server_name         <your_server_name>;

    ssl_certificate     /path/to/ssl_cert;
    ssl_certificate_key /path/to/ssl_cert_key;

    location / {
        proxy_set_header    Host                $host;
        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_http_version  1.1;
        proxy_set_header    Upgrade             $http_upgrade;
        proxy_set_header    Connection          $connection_upgrade;
        proxy_pass          http://127.0.0.1:9000/;
    }
}

No, it's not run behind reverse proxy. Also I noticed that the error I sent in screenshot happens also on Chrome, but at random. Refreshing page helps.

Hello, can you provide the running logs of the nginx ui at the time of this issue?

[FluffyDiscord]

Hi, there is nothing to send. It's a cors issue as mentioned before. You can see the only error on the screenshot. The request was blocked by browser apparently, so nginx doesn't even see it
