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

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

    listen          80;
    listen          [::]:80;

    server_name     <your_server_name>;

}

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

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

    server_name         <your_server_name>;

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.

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
